The crystal structure of BlmI as a model for nonribosomal peptide synthetase peptidyl carrier proteins.
Carrier proteins (CPs) play a critical role in the biosynthesis of various natural products, especially in nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) enzymology, where the CPs are referred to as peptidyl-carrier proteins (PCPs) or acyl-carrier proteins (ACPs), respectively. CPs can either be a domain in large multifunctional polypeptides or standalone proteins, termed ...
متن کاملChain Initiation in the Leinamycin-producing Hybrid Nonribosomal Peptide/Polyketide Synthetase from Streptomyces atroolivaceus S-140 DISCRETE, MONOFUNCTIONAL ADENYLATION ENZYME AND PEPTIDYL CARRIER PROTEIN THAT DIRECTLY LOAD
Nonribosomal peptide natural products are biosynthesized from amino acid precursors by nonribosomal peptide synthetases (NRPSs), which are organized into modules. For a typical NRPS initiationmodule, an adenylation (A) domain activates an amino acid and installs it onto a peptidyl carrier protein (PCP) domain as a thioester; an elongation module, which has a condensation (C) domain located betw...
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...
متن کاملPurification, priming, and catalytic acylation of carrier protein domains in the polyketide synthase and nonribosomal peptidyl synthetase modules of the HMWP1 subunit of yersiniabactin synthetase.
The 207-kDa polyketide synthase (PKS) module (residues 1-1895) and the 143-kDa nonribosomal peptidyl synthetase (NRPS) module (1896-3163) of the 350-kDa HMWP1 subunit of yersiniabactin synthetase have been expressed in and purified from Escherichia coli in soluble forms to characterize the acyl carrier protein (ACP) domain of the PKS module and the homologous peptidyl carrier protein (PCP(3)) d...
متن کاملNew Structural Data Reveal the Motion of Carrier Proteins in Nonribosomal Peptide Synthesis
The nonribosomal peptide synthetases (NRPSs) are one of the most promising resources for the production of new bioactive molecules. The mechanism of NRPS catalysis is based around sequential catalytic domains: these are organized into modules, where each module selects, modifies, and incorporates an amino acid into the growing peptide. The intermediates formed during NRPS catalysis are delivere...
