Biosynthetic reconstitution of deoxysugar phosphoramidate metalloprotease inhibitors using an N-P-bond-forming kinase
Phosphoramidon is a potent metalloprotease inhibitor and a widespread tool in cell biology research. It contains a dipeptide backbone that is uniquely linked to a 6-deoxysugar via a phosphoramidate bridge. Herein, we report the identification of a gene cluster for the formation of phosphoramidon and its detailed characterization. In vitro reconstitution of the biosynthesis established TalE as a phosphoramidate-forming kinase and TalC as the glycosyltransferase which installs the l-rhamnose moiety by phosphoester linkage.
Synthesis of the endothelin converting enzyme inhibitor phosphoramidon
Phosphoramidon, an endothelin converting enzyme inhibitor, is synthesized by coupling of a rhamnose derivative with a dichlorophosphate and a suitably protected dipeptide.
