Crystal structure of the termination module of a nonribosomal peptide synthetase.
Nonribosomal peptide synthetases (NRPSs) are modular multidomain enzymes that act as an assembly line to catalyze the biosynthesis of complex natural products. The crystal structure of the 144-kilodalton Bacillus subtilis termination module SrfA-C was solved at 2.6 angstrom resolution. The adenylation and condensation domains of SrfA-C associate closely to form a catalytic platform, with their ...
متن کاملSubstrate recognition by nonribosomal peptide synthetase multi-enzymes.
Nonribosomal peptide synthetases (NRPSs) are giant multi-domain enzymes that catalyse the biosynthesis of many commercially important peptides produced by bacteria and fungi. Several studies over the last decade have shown that many of the individual domains within NRPSs exhibit significant substrate selectivity, which impacts on our ability to engineer NRPSs to produce new bioactive microbial ...
متن کاملLincosamide Synthetase—A Unique Condensation System Combining Elements of Nonribosomal Peptide Synthetase and Mycothiol Metabolism
In the biosynthesis of lincosamide antibiotics lincomycin and celesticetin, the amino acid and amino sugar units are linked by an amide bond. The respective condensing enzyme lincosamide synthetase (LS) is expected to be an unusual system combining nonribosomal peptide synthetase (NRPS) components with so far unknown amino sugar related activities. The biosynthetic gene cluster of celesticetin ...
متن کاملDecoding and reprogramming fungal iterative nonribosomal peptide synthetases
Nonribosomal peptide synthetases (NRPSs) assemble a large group of structurally and functionally diverse natural products. While the iterative catalytic mechanism of bacterial NRPSs is known, it remains unclear how fungal NRPSs create products of desired length. Here we show that fungal iterative NRPSs adopt an alternate incorporation strategy. Beauvericin and bassianolide synthetases have the ...
متن کاملStructure of a eukaryotic nonribosomal peptide synthetase adenylation domain that activates a large hydroxamate amino acid in siderophore biosynthesis.
Nonribosomal peptide synthetases (NRPSs) are large, multidomain proteins that are involved in the biosynthesis of an array of secondary metabolites. We report the structure of the third adenylation domain from the siderophore-synthesizing NRPS, SidN, from the endophytic fungus Neotyphodium lolii. This is the first structure of a eukaryotic NRPS domain, and it reveals a large binding pocket requ...
