Abstract
BACKGROUND The increasing market demand for oligosaccharides has intensified the need for efficient biocatalysts. Glycosyl hydrolases (GHs) are still gaining popularity as biocatalyst for oligosaccharides synthesis owing to its simple reaction and high selectivity. PURPOSE Over the years, research has advanced mainly directing to one goal; to reduce hydrolysis activity of GHs for increased transglycosylation activity in achieving high production of oligosaccharides. DESIGN AND METHODS This review concisely presents the strategies to increase transglycosylation activity of GHs for oligosaccharides synthesis, focusing on controlling the reaction equilibrium, and protein engineering. Various modifications of the subsites of GHs have been demonstrated to significantly modulate the hydrolysis and transglycosylation activity of the enzymes. The clear insight of the roles of each amino acid in these sites provides a platform for designing an enzyme that could synthesize a specific oligosaccharide product. CONCLUSIONS The key strategies presented here are important for future improvement of GHs as a biocatalyst for oligosaccharide synthesis.

Characterization of two novel sialyl N-acetyllactosaminyl nucleotides separated from ovine colostrum. Glycoconj J 2016; 33:789-96. [PMID: 27206414 DOI: 10.1007/s10719-016-9672-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Revised: 04/15/2016] [Accepted: 05/02/2016] [Indexed: 01/31/2023]
Abstract
The milk/colostrum of some mammalian species is known to contain sugar nucleotides including uridine diphosphate (UDP) oligosaccharides in addition to lactose and milk oligosaccharides, but the detailed structures of these UDP oligosaccharides have not so far been clarified. In this study we isolated two UDP-sialyl N-acetyllactosamines from ovine colostrum and characterized them using (1)H-NMR and MALDI-TOFMS spectroscopies. Their structures were found to be Neu5Gc(α2-3)Gal(β1-4)GlcNAcα1-UDP and Neu5Gc(α2-6)Gal(β1-4)GlcNAcα1-UDP.

Abstract
Glycodiversification broadens the scope of natural product-derived drug discovery. The acceptor substrate promiscuity of glucosyltransferase-D (GTF-D), a carbohydrate-processing enzyme from Streptococcus mutans, was expanded by protein engineering. Mutants in a site-saturation mutagenesis library were screened on the fluorescent substrate 4-methylumbelliferone to identify derivatives with improved transglycosylation efficiency. In comparison to the wild-type GTF-D enzyme, mutant M4 exhibited increased transglycosylation capabilities on flavonoid substrates including catechin, genistein, daidzein and silybin, using the glucosyl donor sucrose. This study demonstrated the feasibility of developing natural product glycosyltransferases by engineering transglycosidases that use donor substrates cheaper than NDP-sugars, and gave rise to a series of α-glucosylated natural products that are novel to the natural product reservoir. The solubility of the α-glucoside of genistein and the anti-oxidant capability of the α-glucoside of catechin were also studied.

Abstract
A chemical synthesis of uridine 5'-diphospho-N-acetyllactosamine (Galbeta(1-->4)GlcNAc-UDP; UDP-LacNAc) and Galbeta(1-->3)GlcNAc-UDP is described. Coupling of the disaccharide imidate derivatives with dibenzylphosphate gave the corresponding 1-phosphates, which were condensed with UMP-imidazolate to give the target UDP-oligosaccharides after purification by anion exchange HPLC and gel filtration column chromatography. Using this methodology a variety of oligosaccharide nucleotide analogues can be synthesized. These UDP-oligosaccharides may be useful for finding so-called ;oligosaccharide transferases', the glycosyltransferases which transfer the oligosaccharide moiety onto glycosyl acceptors.

Abstract
Enzymatic synthesis of GlcNAc-terminated poly-N-acetyllactosamine beta-glycosides GlcNAcbeta1,3(Galbeta1,4GlcNAcbeta1,3)(n)Galbeta1,4GlcNAcbeta-pNP (n=1-4) was demonstrated using a transglycosylation reaction of Escherichia freundii endo-beta-galactosidase. The enzyme catalyzed a transglycosylation reaction on GlcNAcbeta1,3Galbeta1,4GlcNAcbeta-pNP (1), which served both as a donor and an acceptor, and converted 1 into p-nitrophenyl beta-glycosides GlcNAcbeta1,3(Galbeta1,4GlcNAcbeta1,3)(1)Galbeta1,4GlcNAcbeta-pNP (2), GlcNAcbeta1,3(Galbeta1,4GlcNAcbeta1,3)(2)Galbeta1,4GlcNAcbeta-pNP (3), GlcNAcbeta1,3(Galbeta1,4GlcNAcbeta1,3)(3)Galbeta1,4GlcNAcbeta-pNP (4) and GlcNAcbeta1,3(Galbeta1,4GlcNAcbeta1,3)(4)Galbeta1,4GlcNAcbeta-pNP (5). When 2 was used as an initial substrate, it led to the preferential synthesis of nonasaccharide beta-glycoside 4 to heptasaccharide beta-glycoside 3. This suggests that 4 is directly synthesized by transferring the tetrasaccharide unit GlcNAcbeta1,3Galbeta1,4GlcNAcbeta1,3Gal to nonreducing end GlcNAc residue of 2 itself. The efficiency of production of poly-N-acetyllactosamines by E. freundii endo-beta-galactosidase was significantly enhanced by the addition of BSA and by a low-temperature condition. Resulting 2 and 3 were shown to be useful for studying endo-beta-galactosidase-catalyzed hydrolytic and transglycosylation reactions.

Abstract
A novel thermostable chimeric beta-galactosidase was constructed by fusing a poly-His tag to the N-terminal region of the beta-galactosidase from Thermus sp. strain T2 to facilitate its overexpression in Escherichia coli and its purification by immobilized metal-ion affinity chromatography (IMAC). The poly-His tag fusion did not affect the activation, kinetic parameters, and stability of the beta-galactosidase. Copper-iminodiacetic acid (Cu-IDA) supports enabled the most rapid adsorption of the His-tagged enzyme, favoring multisubunit interactions, but caused deleterious effects on the enzyme stability. To improve the enzyme purification a selective one-point adsorption was achieved by designing tailor-made low-activated Co-IDA or Ni-IDA supports. The new enzyme was not only useful for industrial purposes but also has become an excellent model to study the purification of large multimeric proteins via selective adsorption on tailor-made IMAC supports.

Abstract
Geobacillus stearothermophilus NRS 2004/3a possesses an oblique surface layer (S-layer) composed of glycoprotein subunits as the outermost component of its cell wall. In addition to the elucidation of the complete S-layer glycan primary structure and the determination of the glycosylation sites, the structural gene sgsE encoding the S-layer protein was isolated by polymerase chain reaction-based techniques. The open reading frame codes for a protein of 903 amino acids, including a leader sequence of 30 amino acids. The mature S-layer protein has a calculated molecular mass of 93,684 Da and an isoelectric point of 6.1. Glycosylation of SgsE was investigated by means of chemical analyses, 600-MHz nuclear magnetic resonance spectroscopy, and matrix-assisted laser desorption ionization-time of flight mass spectrometry. Glycopeptides obtained after Pronase digestion revealed the glycan structure [-->2)-alpha-L-Rhap-(1-->3)-beta-L-Rhap-(1-->2)-alpha-L-Rhap-(1-->](n = 13-18), with a 2-O-methyl group capping the terminal trisaccharide repeating unit at the non-reducing end of the glycan chains. The glycan chains are bound via the disaccharide core -->3)-alpha-l-Rhap-(1-->3)-alpha-L-Rhap-(L--> and the linkage glycose beta-D-Galp in O-glycosidic linkages to the S-layer protein SgsE at positions threonine 620 and serine 794. This S-layer glycoprotein contains novel linkage regions and is the first one among eubacteria whose glycosylation sites have been characterized.
