biosynthetic mechanism for producing the aminocaprolactam moiety in the capuramycin anti‐mycobacterial antibiotics was delineated by using a combined in vivo and in vitro approach. The process is initiated by adenylation and thioesterification of l‐Lys and characterized by an apparently nonenzymatic intramolecular lactamization.

Using the ATP-independent transacylase CapW required for the biosynthesis of capuramycin-type antibiotics, we developed a biocatalytic approach for the synthesis of 43 analogues via a one-step aminolysis reaction from a methyl ester precursor as an acyldonor and various nonnative amines as acyl acceptors. Further examination of the donor substrate scope for CapW revealed that this enzyme can also
