WebThe biosynthesis of the thiopeptide thiomuracin is a well-orchestrated process involving a multitude of posttranslational modifications. We show that six Cys residues of a precursor peptide are first cyclodehydrated and oxidized to thiazoles in an ordered, but nonlinear fashion that is leader-peptide-dependent. Web2.08.3.3.3. Structural analysis of thiomuracin and GE2270A pyridine synthases Atomic resolution structures have been solved for TbtD (Thiomuracin GZ) and PbtD (GE2270A) in complex with leader peptide fragments and product analogs. 70 These structures connect the pyridine synthases to protein homologs and provide some useful insights into the ...
