[PMID: 38762978 DOI: 10.1016/j.bmc.2024.117760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 05/07/2024] [Accepted: 05/13/2024] [Indexed: 05/21/2024]
Abstract
Oncolytic peptides represented potential novel candidates for anticancer treatments especially drug-resistant cancer cell lines. One of the most promising and extensively studied is LTX-315, which is considered as the first in class oncolytic peptide and has entered phase I/II clinical trials. Nevertheless, the shortcomings including poor proteolytic stability, moderate anticancer durability and high synthesis costs may hinder the widespread clinical applications of LTX-315. In order to reduce the synthesis costs, as well as develop derivatives possessing both high protease-stability and durable anticancer efficiency, twenty LTX-315-based derived-peptides were designed and efficiently synthesized. Especially, through solid-phase S-alkylation, as well as the optimized peptide cleavage condition, the derived peptides could be prepared with drastically reduced synthesis cost. The in vitro anticancer efficiency, serum stability, anticancer durability, anti-migration activity, and hemolysis effect were systematically investigated. It was found that derived peptide MS-13 exhibited comparable anticancer efficiency and durability to those of LTX-315. Strikingly, the D-type peptide MS-20, which is the enantiomer of MS-13, was demonstrated to possess significantly high proteolytic stability and sustained anticancer durability. In general, the cost-effective synthesis and stability-guided structural optimizations were conducted on LTX-315, affording the highly hydrolysis resistant MS-20 which possessed durable anticancer activity. Meanwhile, this study also provided a reliable reference for the future optimization of anticancer peptides through the solid-phase S-alkylation and L-type to D-type amino acid substitutions.

Xu H, Fu XY, Bao YX, Zhu SY, Xu Z, Song M, Qi YK, Li Z, Du SS. d-type peptides based fluorescent probes for "turn on" sensing of heparin. Bioorg Chem 2024; 147:107356. [PMID: 38604021 DOI: 10.1016/j.bioorg.2024.107356] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2024] [Revised: 03/26/2024] [Accepted: 04/06/2024] [Indexed: 04/13/2024]
Abstract
Developing "turn on" fluorescent probes was desirable for the detection of the effective anticoagulant agent heparin in clinical applications. Through combining the aggregation induced emission (AIE) fluorogen tetraphenylethene (TPE) and heparin specific binding peptide AG73, the promising "turn on" fluorescent probe TPE-1 has been developed. Nevertheless, although TPE-1 could achieve the sensitive and selective detection of heparin, the low proteolytic stability and undesirable poor solubility may limit its widespread applications. In this study, seven TPE-1 derived fluorescent probes were rationally designed, efficiently synthesized and evaluated. The stability and water solubility were systematically estimated. Especially, to achieve real-time monitoring of proteolytic stability, the novel Abz/Dnp-based "turn on" probes that employ the internally quenched fluorescent (IQF) mechanism were designed and synthesized. Moreover, the detection ability of synthetic fluorescent probes for heparin were systematically evaluated. Importantly, the performance of d-type peptide fluorescent probe XH-6 indicated that d-type amino acid substitutions could significantly improve the proteolytic stability without compromising its ability of heparin sensing, and attaching solubilizing tag 2-(2-aminoethoxy) ethoxy) acid (AEEA) could greatly enhance the solubility. Collectively, this study not only established practical strategies to improve both the water solubility and proteolytic stability of "turn on" fluorescent probes for heparin sensing, but also provided valuable references for the subsequent development of enzymatic hydrolysis-resistant d-type peptides based fluorescent probes.

An Enzyme-Cleavable Solubilizing-Tag Facilitates the Chemical Synthesis of Mirror-Image Proteins. Angew Chem Int Ed Engl 2024; 63:e202318897. [PMID: 38326236 DOI: 10.1002/anie.202318897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/02/2024] [Accepted: 02/07/2024] [Indexed: 02/09/2024]
Abstract
Mirror-image proteins (D-proteins) are useful in biomedical research for purposes such as mirror-image screening for D-peptide drug discovery, but the chemical synthesis of many D-proteins is often low yielding due to the poor solubility or aggregation of their constituent peptide segments. Here, we report a Lys-C protease-cleavable solubilizing tag and its use to synthesize difficult-to-obtain D-proteins. Our tag is easily installed onto multiple amino acids such as DLys, DSer, DThr, and/or the N-terminal amino acid of hydrophobic D-peptides, is impervious to various reaction conditions, such as peptide synthesis, ligation, desulfurization, and transition metal-mediated deprotection, and yet can be completely removed by Lys-C protease under denaturing conditions to give the desired D-protein. The efficacy and practicality of the new method were exemplified in the synthesis of two challenging D-proteins: D-enantiomers of programmed cell death protein 1 IgV domain and SARS-CoV-2 envelope protein, in high yield. This work demonstrates that the enzymatic cleavage of solubilizing tags under denaturing conditions is feasible, thus paving the way for the production of more D-proteins.

Abstract
Oncolytic peptides represent promising novel candidates for anticancer treatments. In our efforts to develop oncolytic peptides possessing both high protease stability and durable anticancer efficiency, three rounds of optimization were conducted on the first-in-class oncolytic peptide LTX-315. The robust synthetic method, in vitro and in vivo anticancer activity, and anticancer mechanism were investigated. The D-type peptides represented by FXY-12 possessed significantly improved proteolytic stability and sustained anticancer efficiency. Strikingly, the novel hybrid peptide FXY-30, containing one FXY-12 and two camptothecin moieties, exhibited the most potent in vitro and in vivo anticancer activities. The mechanism explorations indicated that FXY-30 exhibited rapid membranolytic effects and induced severe DNA double-strand breaks to trigger cell apoptosis. Collectively, this study not only established robust strategies to improve the stability and anticancer potential of oncolytic peptides but also provided valuable references for the future development of D-type peptides-based hybrid anticancer chemotherapeutics.

Abstract
Many cell-surface receptors are promising targets for chemical synthesis because of their critical roles in disease development. This synthetic approach enables investigations by racemic protein crystallography and ligand discovery by mirror-image methodologies. However, due to their complex nature, the chemical synthesis of a receptor can be a significant challenge. Here, we describe the chemical synthesis and folding of a central, cysteine-rich domain of the cell-surface receptor tumor necrosis factor 1 which is integral to binding of the cytokine TNF-α, namely, TNFR-1 CRD2. Racemic protein crystallography at 1.4 Å confirmed that the native binding conformation was preserved, and TNFR-1 CRD2 maintained its capacity to bind to TNF-α (KD ≈ 7 nM). Encouraged by this discovery, we carried out mirror-image phage display using the enantiomeric receptor mimic and identified a d-peptide ligand for TNFR-1 CRD2 (KD = 1 μM). This work demonstrated that cysteine-rich domains, including the central domains, can be chemically synthesized and used as mimics for investigations.

Abstract
The S-palmitoylation on Cys residue and O-acetylation on Ser/Thr residues are two types of base-labile post-translational modifications (PTMs) in cells. The lability of these PTMs to bases and nucleophiles makes the peptides/proteins bearing S-palmitoyl or O-acetyl groups challenging synthetic targets, which cannot be prepared via the standard Fmoc-SPPS and native chemical ligation. In this review, we summarized the efforts towards their preparation in the past 40 years, with the focus on the evolution of synthetic methods.

Abstract
Membrane-associated D-proteins are an important class of synthetic molecules needed for D-peptide drug discovery, but their chemical synthesis using canonical ligation methods such as native chemical ligation is often hampered by the poor solubility of their constituent peptide segments. Here, we describe a Backbone-Installed Split Intein-Assisted Ligation (BISIAL) method for the synthesis of these proteins, wherein the native L-forms of the N- and C-intein fragments of the unique consensus-fast (Cfa) (i.e. L-CfaN and L-CfaC ) are separately installed onto the two D-peptide segments to be ligated via a removable backbone modification. The ligation proceeds smoothly at micromolar (μM) concentrations under strongly chaotropic conditions (8.0 M urea), and the subsequent removal of the backbone modification groups affords the desired D-proteins without leaving any "ligation scar" on the products. The effectiveness and practicality of the BISIAL method are exemplified by the synthesis of the D-enantiomers of the extracellular domains of T cell immunoglobulin and ITIM domain (TIGIT) and tropomyosin receptor kinase C (TrkC). The BISIAL method further expands the chemical protein synthesis ligation toolkit and provides practical access to challenging D-protein targets.

Abstract
Total chemical protein synthesis provides access to entire D-protein enantiomers enabling unique applications in molecular biology, structural biology, and bioactive compound discovery. Key enzymes involved in the central dogma of molecular biology have been prepared in their D-enantiomeric forms facilitating the development of mirror-image life. Crystallization of a racemic mixture of L- and D-protein enantiomers provides access to high-resolution X-ray structures of polypeptides. Additionally, D-enantiomers of protein drug targets can be used in mirror-image phage display allowing discovery of non-proteolytic D-peptide ligands as lead candidates. This review discusses the unique applications of D-proteins including the synthetic challenges and opportunities.

Abstract
Chemical synthesis of hydrophobic proteins presents a formidable task as they are often difficultly achieved via peptide synthesis, purification, and peptide ligation. Thus, peptide solubilizing strategies are needed to integrate with peptide ligation to achieve protein total synthesis. Herein, we report a tunable backbone modification strategy, taking advantage of the tunable stability of the Cys/Pen ligation intermediate, which allows for readily introducing a solubilizing tag for both peptide purification and ligation processes. The effectiveness of this strategy was demonstrated by the chemical synthesis of interleukin-2.

Abstract
Proteins modified in a controlled manner with artificial moieties such as fluorophores or affinity tags have been shown to be a powerful tool for functional or structural analysis of proteins. A reliable way to prepare proteins with a well-defined modification is protein synthesis. Although many successful syntheses have been reported, the poor aqueous solubility of synthetic intermediates causes difficulty in the chemical synthesis of proteins. Here we describe a solubilizing strategy for poorly soluble peptides which uses chemoselective incorporation of a hydrophilic tag onto a hydrazide in a peptide. We found that a hydrophilic tag possessing a dialkoxybenzaldehyde moiety can react with peptide hydrazides through reductive N-alkylation. No protecting groups are required for this reaction, and peptides modified in this way show enhanced solubility and consequently good peak separation during HPLC purification. The tag can be removed subsequently by treatment with trifluoroacetic acid to generate a free hydrazide, which can be converted in a one-pot reaction to a thioester for further modification. This method was validated by synthesis of a Lys63-linked ubiquitin dimer derivative. This late-stage solubilization can be applied in principal to any peptide and opens the possibility of the synthesis of proteins that have previously been considered inaccessible due to their poor solubility.

Abstract
Protein phosphorylation is a crucial regulator of protein and cellular function, yet, despite identifying an enormous number of phosphorylation sites, the role of most is still unclear. Each phosphoform, the particular combination of phosphorylations, of a protein has distinct and diverse biological consequences. Aberrant phosphorylation is implicated in the development of many diseases. To investigate their function, access to defined protein phosphoforms is essential. Materials obtained from cells often are complex mixtures. Recombinant methods can provide access to defined phosphoforms if site-specifically acting kinases are known, but the methods fail to provide homogenous material when several amino acid side chains compete for phosphorylation. Chemical and chemoenzymatic synthesis has provided an invaluable toolbox to enable access to previously unreachable phosphoforms of proteins. In this review, we selected important tools that enable access to homogeneously phosphorylated protein and discuss examples that demonstrate how they can be applied. Firstly, we discuss the synthesis of phosphopeptides and proteins through chemical and enzymatic means and their advantages and limitations. Secondly, we showcase illustrative examples that applied these tools to answer biological questions pertaining to proteins involved in signal transduction, control of transcription, neurodegenerative diseases and aggregation, apoptosis and autophagy, and transmembrane proteins. We discuss the opportunities and challenges in the field.

Abstract
Small membrane proteins represent a subset of recently discovered small proteins (≤100 amino acids), which are a ubiquitous class of emerging regulators underlying bacterial adaptation to environmental stressors. Until relatively recently, small open reading frames encoding these proteins were not designated genes in genome annotations. Therefore, our understanding of small protein biology was primarily limited to a few candidates associated with previously characterized larger partner proteins. Following the first systematic analyses of small proteins in Escherichia coli over a decade ago, numerous small proteins across different bacteria have been uncovered. An estimated one-third of these newly discovered proteins in E. coli are localized to the cell membrane, where they may interact with distinct groups of membrane proteins, such as signal receptors, transporters, and enzymes, and affect their activities. Recently, there has been considerable progress in functionally characterizing small membrane protein regulators aided by innovative tools adapted specifically to study small proteins. Our review covers prototypical proteins that modulate a broad range of cellular processes, such as transport, signal transduction, stress response, respiration, cell division, sporulation, and membrane stability. Thus, small membrane proteins represent a versatile group of physiology regulators at the membrane and the whole cell. Additionally, small membrane proteins have the potential for clinical applications, where some of the proteins may act as antibacterial agents themselves while others serve as alternative drug targets for the development of novel antimicrobials.

Abstract
Disulfide-rich proteins are useful as drugs or tool molecules in biomedical studies, but their synthesis is complicated by the difficulties associated with their folding. Here, we describe a removable glycosylation modification (RGM) strategy that expedites the chemical synthesis of correctly folded proteins with multiple or even interchain disulfide bonds. Our strategy comprises the introduction of simple O-linked β-N-acetylglucosamine (O-GlcNAc) groups at the Ser/Thr sites that effectively improve the folding of disulfide-rich proteins by stabilization of their folding intermediates. After folding, the O-GlcNAc groups can be efficiently removed using O-GlcNAcase (OGA) to afford the correctly folded proteins. Using this strategy, we completed the synthesis of correctly folded hepcidin, an iron-regulating hormone bearing four pairs of disulfide-bonds, and the first total synthesis of correctly folded interleukin-5 (IL-5), a 26 kDa homodimer cytokine responsible for eosinophil growth and differentiation.

Abstract
Chemical synthesis can provide hydrophobic proteins with natural or man-made modifications (e.g. S-palmitoylation, site-specific isotope labeling and mirror-image proteins) that are difficult to obtain through the recombinant expression technology. The difficulty of chemical synthesis of hydrophobic proteins stems from the hydrophobic nature. Removable backbone modificaiton (RBM) strategy has been developed for solubilizing the hydrophobic peptides/proteins. Here we take the chemical synthesis of a S-palmitoylated peptide as an example to describe the detailed procedure of RBM strategy. Three critical steps of this protocol are: (1) installation of Lys6-tagged RBM groups into the peptides by Fmoc (9-fluorenylmethyloxycarbonyl) solid-phase peptide synthesis, (2) chemical ligation of the peptides, and (3) removal of the RBM tags by TFA (trifluoroacetic acid) cocktails to give the target peptide.

Abstract
Protein S-fatty acylation or S-palmitoylation is a reversible and regulated lipid post-translational modification (PTM) in eukaryotes. Loss-of-function mutagenesis studies have suggested important roles for protein S-fatty acylation in many fundamental biological pathways in development, neurobiology, and immunity that are also associated with human diseases. However, the hydrophobicity and reversibility of this PTM have made site-specific gain-of-function studies more challenging to investigate. In this review, we summarize recent chemical biology approaches and methods that have enabled site-specific gain-of-function studies of protein S-fatty acylation and the investigation of the mechanisms and significance of this PTM in eukaryotic biology.

Abstract
Caveolin-1, which is an essential protein for caveola formation, was chemically synthesized. It is composed of 177 amino acid residues, is triply palmitoylated at the C-terminal region, and is inserted into the lipid bilayer to form a V-shaped structure in the middle of the polypeptide chain. The entire sequence was divided into five peptide segments, each of which was synthesized by the solid-phase method. To improve the solubility of the C-terminal region, O-acyl isopeptide structures were incorporated. After ligation by the thioester method and the introduction of the palmitoyl groups, all the protecting groups were removed and the isopeptide structures were converted into the native peptide bond. Finally, the obtained polypeptide was successfully inserted into bicelles, thus showing the success of the synthesis.

Abstract
Hydrophobic latent C-terminal thioesters were converted into thioesters, and were also coupled with cysteine in one-pot reactions, using conditions generally compatible with hydrophobic materials. The reaction conditions (ethanethiol and triethylamine in a mixture of DMF and THF) are compatible with acid-labile protecting groups (Boc/t-Bu) that are standard in Fmoc peptide synthesis.

Abstract
A two-step synthesis for methionine-containing hydrophobic and/or aggregation-prone peptides is presented that takes advantage of the reversibility of methionine oxidation. The use of polar methionine sulfoxide as a building block in solid-phase peptide synthesis improves the synthesis quality and yields the crude peptide, with significantly improved solubility compared to the reduced species. This facilitates the otherwise often laborious peptide purification by high-performance liquid chromatography. The subsequent reduction proceeds quantitatively. This approach has been optimised with the methionine-rich Tar-DNA-binding protein 43 (307-347), but is also more generally applicable, as demonstrated by the syntheses of human calcitonin and two aggregation-prone peptides from the human prion protein.

Abstract
A novel late-stage solubilization of peptides using hydrazides is described. A solubilizing tag was attached through a selective N-alkylation at a hydrazide moiety with the aid of a 2-picoline-borane complex in 50% acetic acid-hexafluoro-2-propanol. The tag, which tolerates ligation and desulfurization conditions, can be detached by a Cu-mediated selective oxidative hydrolysis of the N-alkyl hydrazide. This new method was validated through the synthesis of HIV-1 protease.

Abstract
![]()
The chemical synthesis of a highly hydrophobic membrane-associated peptide by native
chemical ligation (NCL) in an ionic liquid (IL) [C2mim][OAc]/buffer mixture
was achieved by employing peptide concentrations up to 11 mM. NCL was studied at
different pH and water content and compared to several “gold-standard”
ligation protocols. The optimized reaction protocol for the NCL in IL required the
addition of 40% water and pH adjustment to 7.0–7.5, resulting in ligation yields
of up to 80–95% within 1 to 4 h. This new ligation protocol is generally
applicable and outperforms current “gold-standard” NCL methods.

Abstract
One of the main limitations encountered during the chemical synthesis of proteins through native chemical ligation (NCL) is the limited solubility of some of the peptide segments. The most commonly used solution to overcome this problem is to derivatize the segment with a temporary solubilizing tag. Conveniently, the tag can be introduced on the thioester segment in such a way that it is removed concomitantly with the NCL reaction. We herein describe a generalization of this approach to N-terminal cysteinyl segment counterparts, using a straightforward synthetic approach that can be easily automated from commercially available building blocks, and applied it to a well-known problematic target, SUMO-2.

Abstract
Work from our laboratories over the last 35 years that has focused on Ste2p, a G protein-coupled receptor (GPCR), and its tridecapeptide ligand α-factor is reviewed. Our work utilized the yeast Saccharomyces cerevisiae as a model system for understanding peptide-GPCR interactions. It explored the structure and function of synthetic α-factor analogs and biosynthetic receptor domains, as well as designed mutations of Ste2p. The results and conclusions are described using the nuclear magnetic resonance interrogation of synthetic Ste2p transmembrane domains (TMs), the fluorescence interrogation of agonist and antagonist binding, the biochemical crosslinking of peptide analogs to Ste2p, and the phenotypes of receptor mutants. We identified the ligand-binding domain in Ste2p, the functional assemblies of TMs, unexpected and interesting ligand analogs; gained insights into the bound α-factor structure; and unraveled the function and structures of various Ste2p domains, including the N-terminus, TMs, loops connecting the TMs, and the C-terminus. Our studies showed interactions between specific residues of Ste2p in an active state, but not resting state, and the effect of ligand activation on the dimerization of Ste2p. We show that, using a battery of different biochemical and genetic approaches, deep insight can be gained into the structure and conformational dynamics of GPCR-peptide interactions in the absence of a crystal structure.

Abstract
Phosphorylation, one of the important protein post-translational modifications, is involved in many essential cellular processes. Site-specifical and homogeneous phosphoproteins can be used as probes for elucidating the protein phosphorylation network and as potential therapeutics for interfering their involved biological events. However, the generation of phosphoproteins has been challenging owing to the limitation of chemical synthesis and protein expression systems. Despite the pioneering discoveries in phosphoprotein synthesis, over the past decade, great progresses in this field have also been made to promote the biofunctional exploration of protein phosphorylation largely. Therefore, in this review, we mainly summarize recent advances in phosphoprotein synthesis, which includes five sections: 1) synthesis of the nonhydrolyzable phosphorylated amino acid mimetic building blocks, 2) chemical total and semisynthesis strategy, 3) in-cell and in vitro genetic code expansion strategy, 4) the late-stage modification strategy, 5) nonoxygen phosphoprotein synthesis.

Abstract
Chemists have been interested in the N-alkylation of a peptide bond because such a modification alters the conformation of the amide bond, interferes with hydrogen bond formation, and changes other properties of the peptide (e.g., solubility). This modification also opens the door for attaching functional groups for various applications. Nonetheless, the irreversibility of some of these modifications and the harsh conditions required for their removal currently limits the wide utility of this approach. Herein, we report applying a propargyl group for peptide bond modification at diverse junctions, which can be removed under mild and aqueous conditions via treatment with gold(I). Considering the straightforward conditions for both the installation and removal of this group, the propargyl group provides access to the benefits of backbone N-alkylation, while preserving the ability for on-demand depropargylation and full recovery of the native amide bond. This reversible modification was found to improve solid-phase peptide synthesis as demonstrated in the chemical synthesis of NEDD8 protein, without the use of special dipeptide analogues. Also, the reported approach was found to be useful in decaging a broad range of propargyl-based protecting groups used in chemical protein synthesis. Remarkably, reversing the order of the two residues in the propargylation site resulted in rapid amide bond cleavage, which extends the applicability of this approach beyond a removable backbone modification to a cleavable linker. The easy attach/detach of this functionality was also examined in loading and releasing of biotinylated peptides from streptavidin beads.

Abstract
Solid phase peptide synthesis (SPPS) provides the possibility to chemically synthesize peptides and proteins. Applying the method on hydrophilic structures is usually without major drawbacks but faces extreme complications when it comes to "difficult sequences." These includes the vitally important, ubiquitously present and structurally demanding membrane proteins and their functional parts, such as ion channels, G-protein receptors, and other pore-forming structures. Standard synthetic and ligation protocols are not enough for a successful synthesis of these challenging sequences. In this review we highlight, summarize and evaluate the possibilities for synthetic production of "difficult sequences" by SPPS, native chemical ligation (NCL) and follow-up protocols.

Abstract
A new robust strategy was reported for the epimerization-free synthesis of C-terminal Cys-containing peptide acids through mercaptoethanol-mediated hydrolysis of peptide thioesters prepared in situ from peptide hydrazides. This simple-to-operate and highly efficient method avoids the use of derivatization reagents for resin modification, thus providing a practical avenue for the preparation of C-terminal Cys-containing peptide acids.

Chemical protein synthesis has been proved as an efficient way to afford medium-sized proteins with high homogeneity in workable quantities for various biochemical, structural, and functional studies. In particular, chemical protein synthesis has enabled access to proteins that are difficult or impossible to prepare by molecular biology approaches, such as those with post-translational modifications and mirror-image proteins. One prominent example is related to ubiquitination, a well-known modification that mediates a variety of cellular processes (e.g., proteasomal degradation). Ubiquitination is considered as a modification that is difficult to introduce into proteins in a test tube to generate ubiquitin (Ub) conjugates with high homogeneity with respect to the chain length and the anchored Lys residue in workable quantities to perform the biochemical and biophysical studies. Chemical protein synthesis has emerged as a powerful approach to prepare Ub conjugates for studies aiming to understand ubiquitination in great detail and decipher its roles in cell processes. Nevertheless, in order to answer more challenging questions in this field, it has been clear that researchers must also prepare Ub conjugates with increased size and complexity. Employing solid-phase peptide synthesis and chemoselective ligation, chemical protein synthesis offers a powerful way to furnish polypeptides composed of 100-200 residues. However, to synthesize larger proteins such as Ub conjugates, longer and more segments are required. This on the other hand leads to difficulties related to solubility, purification, ligation, and late-stage modifications. These challenges have encouraged us to explore more practical synthetic tools to facilitate the synthesis of complex Ub conjugates. In this Account, we summarize the synthetic tools that we have developed to achieve these goals. These include (1) δ-mercaptolysine-mediated isopeptide chemical ligation, (2) chemical synthesis of Ub building blocks, (3) palladium-mediated deprotection of key side chains during protein synthesis, (4) one-pot ligation and desulfurization, and (5) improving the solubility of peptide segments. The developed chemical toolbox has been a key for our successes in the synthesis of diverse and complex Ub conjugates. In this Account, we describe our approaches for generating various Ub conjugates, including (1) the K48 tetra-Ub chain composed of 304 amino acids, (2) the ubiquitinated histones and their analogues made of >200 amino acids, (3) the di-Ub-SUMO-2 hybrid chain composed of 245 amino acids, and (4) the 53 kDa tetra-Ub-α-globin composed of 472 amino acids, which represents the largest protein composed of natural amino acids ever made using chemical protein synthesis. The last target, Flag-Ub-Ub-Ub-Myc-Ub-(HA-α-globin), was prepared in the labeled form where the proximal Ub and distal Ub in the chain were labeled with Myc and Flag tags, respectively, while the α-globin was labeled with the HA tag. Applying the tetra-Ub-α-globin in proteasomal degradation studies assisted us to shed light on the proteolytic signal and the fates of the Ub moieties in the chains. Although these developments have contributed to the synthesis of interesting and challenging targets related to Ub signaling, several other targets may enforce new synthetic challenges. Hence, there is still a need to optimize the current synthetic tools and explore novel synthetic approaches to facilitate this process.

Abstract
Hydrophobic membrane peptides/proteins having low water solubility are often difficult to prepare. To overcome this issue, temporal introduction of solubilizing tags has been demonstrated to be beneficial. Following our recent work on the solubilization of a difficult target by using a hydrophilic oligo-Lys tag bearing a trityl linker (Trt-K method), this paper describes a comparative study of the solubilizing abilities of several peptidic trityl tags containing Lys, Arg, Glu, Asn, Nε-tri-Me-Lys or Cys-sulfonate using two hydrophobic model peptides. Among the tags evaluated, that containing Nε-tri-Me-Lys exhibits superior solubilizing ability.

Abstract
In the continuous exploration of the VHH chemistry, biochemistry and therapeutic future use, we investigated two different production strategies of this small antibody-like protein, using an anti-HER2 VHH as a model. The total chemical synthesis of the 125 amino-acid peptide was performed with reasonable yield, even if optimization will be necessary to upgrade this kind of production. In parallel, we expressed the same sequence in two different hosts: Escherichia coli and Pichia pastoris. Both productions were successful and led to a fair amount of VHHs. The integrity and conformation of the VHH were characterized by complementary mass spectrometry approaches, while surface plasmon resonance experiments were used to assess the VHH recognition capacity and affinity toward its "antigen." Using this combination of orthogonal techniques, it was possible to show that the three VHHs-whether synthetic or recombinant ones-were properly and similarly folded and recognized the "antigen" HER2 with similar affinities, in the nanomolar range. This opens a route toward further exploration of modified VHH with unnatural amino acids and subsequently, VHH-drug conjugates.

Abstract
During the total chemical synthesis of the water-soluble globular Haemophilus Influenzae DNA ligase (Hin-Lig), we observed the surprising phenomenon of a soluble peptide segment that failed to undergo native chemical ligation. Based on dynamic light scattering and transmission electron microscopy experiments, we determined that the peptide formed soluble colloidal particles in a homogeneous solution containing 6 m guanidine hydrochloride. Conventional peptide performance-improving strategies, such as installation of a terminal/side-chain Arg tag or O-acyl isopeptide, failed to enable the reaction, presumably because of their inability to disrupt the formation of soluble colloidal particles. However, a removable backbone modification strategy recently developed for the synthesis of membrane proteins did disrupt the formation of the colloids, and the desired ligation of this soluble but unreactive system was eventually accomplished. This work demonstrates that an appropriate solution dispersion state, in addition to good peptide solubility, is a prerequisite for successful peptide ligation.

Abstract
E3 ligases play a critical role in ubiquitin (Ub) conjugation cascades, and any aberration in their activity is associated with a number of diseases. Advancement in our knowledge of understanding the roles of HECT E3s requires biochemical tools such as activity-based probes (ABPs). In this study we developed a novel dehydroalanine (Dha)-based E2-Ub ABP using a strategy that is a combination of practical hydrazide-based native chemical ligation and sequential Dha formation. The probe could be used for labeling HECT E3s not only in vitro but also in endogenous cellular contexts. Our easy-to-implement method is expected to be useful for the preparation of Dha based Ub family E2 conjugate ABPs.
