Thiotemplate mechanism
WebAlthough structurally diverse, most of the nonribosomal peptides share a common mode of synthesis, the multienzyme thiotemplate mechanism facilitated by peptide synthetases. This alternative machinery for peptide synthesis, which depends on a protein template, seems to be necessary for introducing the required variability into the peptides ... WebJan 15, 2002 · Laland and Zimmer (1973) called such a mechanism of peptide biosynthesis the ‘protein thiotemplate mechanism’ and Lipmann et al. (1971) termed it the ‘protein template mechanism’.

WebJan 5, 2024 · Nonribosomal peptide synthetases (NRPSs) are modular enzymes that use a thiotemplate mechanism to assemble the peptide backbones of structurally diverse and …
WebAug 6, 2015 · The synthesis proceeds by a thiotemplate mechanism whereby intermediates are covalently attached to the PKS. The release of the final polyketide is catalyzed by the terminal thioesterase (TE) domain through hydrolysis, transesterification, or macrocyclization. The PKS 6-deoxyerythronolide B synthase (DEBS) produces the 14 … WebAlthough the precise function of the gene products needs further clarification, a biosynthetic pathway based on a multienzyme thiotemplate mechanism allowing a step-by-step synthesis of the whole chromopeptide molecule can be postulated.
WebJan 1, 2010 · The thiotemplate mechanism is catalyzed by nonribosomal peptide synthetases (NRPSs). NRPSs are often called multienzyme systems because of the coexistence of typical adenylation domains, peptidyl carrier domains, specific epimerization domains, N-methylation domains, and thiolase domains (Vater et al. 1985; Stein et al … Webthiotemplate mechanism. A non-ribosomal, non- RNA -dependent mechanism for the synthesis of bacterial cyclic oligo peptide antibiotics (e.g. gramicidin S) in which the amino acid residues are first transferred from amino acid adenylates to thiol groups of a peptide synthetase that then collects the residues, in sequence, on a phosphopantetheine ...
WebThe biosynthetic activity involves the multicarrier thiotemplate mechanism and the enzyme is organized in structural domains that place it in the family of peptide synthetases, a class of enzymes involved in peptidic secondary-metabolite synthesis.
