Abstract: Several soil-derived Actinobacteria produce secondary metabolites that are proven specific and potent inhibitors of the human angiotensin-I-converting enzyme (ACE), a key target for the modulation of hypertension through its role in the renin–angiotensin–aldosterone system. K-26-DCP is a zinc dipeptidyl carboxypeptidase (DCP) produced by Astrosporangium hypotensionis, and an ancestral homologue of ACE. Here we report the high-resolution crystal structures of K-26-DCP and of its complex with the natural microbial tripeptide product K-26. The experimental results provide the structural basis for better understanding the specificity of K-26 for human ACE over bacterial DCPs.
