This enzyme may also play a role in N-formylation of the first amino acid residue in the synthesized dipeptide. Publication Abstract from PubMed Nonribosomal depsipeptides are natural products composed of amino and hydroxy acid residues. The hydroxy acid residues often derive from alpha-keto acids, reduced by ketoreductase domains in the depsipeptide synthetases. Biochemistry and structures reveal the mechanism of discrimination for alpha-keto acids and a remarkable architecture: flanking intact adenylation and ketoreductase domains are sequences separated by >1,100 residues that form a split 'pseudoAsub' domain, structurally important for the depsipeptide module's synthetic cycle.
