Changing hands: In the biosynthesis of bombinin H, an isomerase catalyses the inversion of chirality of an amino acid in peptide linkage through a deprotonation/protonation mechanism. We have synthesized two substrate analogues (1) that are potent inhibitors of the enzyme reaction. Our results strongly support a planar transition state, such as an enolate anion intermediate (2).
