Abstract
ABSTRACT
Peptides, biologically occurring oligomers of amino acids linked by amide bonds, are essential for living organisms. Many peptides isolated as natural products have biological functions such as antimicrobial, antivirus and insecticidal activities. Peptides often possess structural features or modifications not found in proteins, including the presence of nonproteinogenic amino acids, macrocyclic ring formation, heterocyclization, N-methylation and decoration by sugars or acyl groups. Nature employs various strategies to increase the structural diversity of peptides. Enzymes that modify peptides to yield mature natural products are of great interest for discovering new enzyme chemistry and are important for medicinal chemistry applications. We have discovered novel peptide modifying enzymes and have identified: (i) a new class of amide bond forming-enzymes; (ii) a pathway to biosynthesize a carbonylmethylene-containing pseudodipeptide structure; and (iii) two distinct peptide epimerases. In this review, an overview of our findings on peptide modifying enzymes is presented.
