Dissecting and exploiting nonribosomal peptide synthetases.
A large number of therapeutically useful cyclic and linear peptides of bacteria or fungal origin are synthesized via a template-directed, nucleic-acid-independent nonribosomal mechanism. This process is carried out by mega-enzymes called nonribosomal peptide synthetases (NRPSs). NRPSs contain repeated coordinated groups of active sites called modules, and each module is composed of several doma...
متن کاملError-prone DnaE2 Balances the Genome Mutation Rates in Myxococcus xanthus DK1622
dnaE is an alpha subunit of the tripartite protein complex of DNA polymerase III that is responsible for the replication of bacterial genome. The dnaE gene is often duplicated in many bacteria, and the duplicated dnaE gene was reported dispensable for cell survivals and error-prone in DNA replication in a mystery. In this study, we found that all sequenced myxobacterial genomes possessed two dn...
متن کاملMechanisms Involved in the Functional Divergence of Duplicated GroEL Chaperonins in Myxococcus xanthus DK1622
The gene encoding the GroEL chaperonin is duplicated in nearly 30% of bacterial genomes; and although duplicated groEL genes have been comprehensively determined to have distinct physiological functions in different species, the mechanisms involved have not been characterized to date. Myxococcus xanthus DK1622 has two copies of the groEL gene, each of which can be deleted without affecting cell...
متن کاملPhylogenetic analysis of condensation domains in the nonribosomal peptide synthetases.
Condensation (C) domains in the nonribosomal peptide synthetases are capable of catalyzing peptide bond formation between two consecutively bound various amino acids. C-domains coincide in frequency with the number of peptide bonds in the product peptide. In this study, a phylogenetic approach was used to investigate structural diversity of bacterial C-domains. Phylogenetic trees show that the ...
متن کاملRegeneration of misprimed nonribosomal peptide synthetases by type II thioesterases.
Nonribosomal peptide synthetases (NRPSs) assemble structurally complex peptides from simple building blocks such as amino and carboxyl acids. Product release by macrocyclization or hydrolysis is catalyzed by a thioesterase domain that is an integrated part of the NRPS enzyme. A second thioesterase of type II (TEII) encoded by a distinct gene associated with the NRPS cluster was previously shown...
