Abstract
Modified cyclic dipeptides represent a widespread class of secondary metabolites with diverse pharmacological activities, including antibacterial, antifungal, and antitumor. Here, we report the structural characterization of the Streptomyces noursei enzyme AlbAB, a cyclodipeptide oxidase (CDO) carrying out α,β-dehydrogenations during the biosynthesis of the antibiotic albonoursin. We show that AlbAB is a megadalton heterooligomeric enzyme filament containing covalently bound flavin mononucleotide cofactors. We highlight that AlbAB filaments consist of alternating dimers of AlbA and AlbB and that enzyme activity is crucially dependent on filament formation. We show that AlbA-AlbB interactions are highly conserved suggesting that other CDO-like enzymes are likely enzyme filaments. As CDOs have been employed in the structural diversification of cyclic dipeptides, our results will be useful for future applications of CDOs in biocatalysis and chemoenzymatic synthesis.

Abstract
Cyclodipeptides from fungi and bacteria are often modified by different tailoring enzymes. They display various biological and pharmacological activities, and some derivatives are used as drugs. In a previous study, we elucidated the function of the silent guatrypmethine gene cluster from Streptomyces cinnamoneus containing a cyclodipeptide synthase (CDPS) core gene gtmA and four genes gtmB-gtmE for tailoring enzymes. The latter are used in this study for the design of modified cyclodipeptides by genetic engineering. Addition of six different cyclodipeptides to the Streptomyces albus transformant harboring gtmB-gtmE led to the detection of different pathway products. Coexpression of five CDPS genes from four Streptomyces strains with gtmB-gtmE resulted in the formation of diketopiperazine derivatives, differing in their modification stages. Our results demonstrate the potential of rational gene combination to increase structural diversity.

Abstract
Heterologous expression of a cdps-p450 locus from Streptomyces sp. NRRL S-1521 led to the identification of guanitrypmycin D1, a new guaninylated diketopiperazine. The cytochrome P450 GutD1521 catalyzed the regiospecific transfer of guanine to C-2 of the indole ring of cyclo-(l-Trp-l-Tyr) via a C-C linkage and represents a new chemical transformation within this enzyme class. Furthermore, GutD1521 efficiently accepts several other tryptophan-containing cyclodipeptides or derivatives for regiospecific coupling with guanine, thus generating different guanitrypmycin analogs.

Abstract
Tailoring enzymes are important modification biocatalysts in natural product biosynthesis. We report herein six orthologous two‐gene clusters for mycocyclosin and guatyromycine biosynthesis. Expression of the cyclodipeptide synthase genes gymA1–gymA6 in Escherichia coli resulted in the formation of cyclo‐l‐Tyr‐l‐Tyr as the major product. Reconstruction of the biosynthetic pathways in Streptomyces albus and biochemical investigation proved that the cytochrome P450 enzymes GymB1–GymB6 act as both intramolecular oxidases and intermolecular nucleobase transferases. They catalyze not only the oxidative C−C coupling within cyclo‐l‐Tyr‐l‐Tyr, leading to mycocyclosin, but also its connection with guanine and hypoxanthine, and are thus responsible for the formation of tyrosine‐containing guatyromycines, instead of the reported tryptophan‐nucleobase adducts. Phylogenetic data suggest the presence of at least 47 GymB orthologues, indicating the occurrence of a widely distributed enzyme class.

Abstract
Prenylation can impart pharmacological advantages to bioactive compounds. Global genome mining for prenylated cyclodipeptides identified a gczABC BGC from Streptomyces griseocarneus 132 containing a cyclodipeptide synthase and two prenyltransferase genes. Subsequent heterologous expression allowed isolation and characterization of griseocazines, which displayed potent neuroprotective activity. Further biotransformation analyses revealed that prenyltransferases GczB and GczC catalyzed the stereospecific prenylation of cWW and attached geranyl and farnesyl groups to a cyclodipeptide scaffold, respectively.
