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.
