Biosynthesis of the antibiotic nonribosomal peptide penicillin in baker's yeast
Fungi are a valuable source of enzymatic diversity and therapeutic natural products including antibiotics. Here we engineer the baker's yeast Saccharomyces cerevisiae to produce and secrete the antibiotic penicillin, a beta-lactam nonribosomal peptide, by taking genes from a filamentous fungus and directing their efficient expression and subcellular localization. Using synthetic biology tools c...
متن کاملBiosynthesis of isonitrile lipopeptides by conserved nonribosomal peptide synthetase gene clusters in Actinobacteria.
A putative lipopeptide biosynthetic gene cluster is conserved in many species of Actinobacteria, including Mycobacterium tuberculosis and M. marinum, but the specific function of the encoding proteins has been elusive. Using both in vivo heterologous reconstitution and in vitro biochemical analyses, we have revealed that the five encoding biosynthetic enzymes are capable of synthesizing a famil...
متن کاملEpsilon-poly-L-lysine dispersity is controlled by a highly unusual nonribosomal peptide synthetase.
Epsilon-Poly-L-lysine (epsilon-PL) consists of 25-35 L-lysine residues in isopeptide linkages and is one of only two amino acid homopolymers known in nature. Elucidating the biosynthetic mechanism of epsilon-PL should open new avenues for creating novel classes of biopolymers. Here we report the purification of an epsilon-PL synthetase (Pls; 130 kDa) and the cloning of its gene from an epsilon-...
متن کاملLeinamycin biosynthesis revealing unprecedented architectural complexity for a hybrid polyketide synthase and nonribosomal peptide synthetase.
A 135,638 bp DNA region that encompasses the leinamycin (LNM) biosynthetic gene cluster was sequenced from Streptomyces atroolivaceus S-140. The boundaries of the lnm cluster were defined by systematic inactivation of open reading frames within the sequenced region. The lnm cluster spans 61.3 kb of DNA and consists of 27 genes encoding nonribosomal peptide synthetase (NRPS), polyketide synthase...
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 ...
