Circular logic: nonribosomal peptide-like macrocyclization with a ribosomal peptide catalyst

J Am Chem Soc. 2010 Nov 10;132(44):15499-501. doi: 10.1021/ja1067806.

Abstract

A protease from ribosomal peptide biosynthesis macrocyclizes diverse substrates, including those resembling nonribosomal peptide and hybrid polyketide-peptide products. The proposed mechanism is analogous to thioesterase-catalyzed chemistry, but the substrates are amide bonds rather than thioesters.
