英文摘要 | Thiopeptides are a class of clinically interesting and highly modified peptide antibiotics. Their biosyntheses share a common paradigm for characteristic core formation but differ in tailoring to afford individual members. Herein we report an unusual deesterification-amidation process in thiostrepton maturation to furnish the terminal amide moiety. TsrB, serving as a carboxylesterase, catalyzes the hydrolysis of the methyl ester intermediate to provide the carboxylate intermediate, which can be converted to the amide product by an amidotransferase, TsrC. These findings revealed a C-terminal methylation of the precursor peptide, which is cryptic in thiostrepton biosynthesis but potentially common in the formation of its homologous series of thiopeptides that vary in the C-terminal form as methyl ester, carboxylate, or amide. |
