Hydrogenobyrinic acid

Web4 aug. 2016 · The CobB amidotransferase uses ATP and glutamine to amidate the acetic acid side chains a and c, producing hydrogenobyrinic acid a,c-diamide. The latter is the substrate for the CobNST cobalt ion chelatase (EC 6.6.1.2), which yields cobyrinic acid a,c-diamide upon insertion of the Co ion into the ring.
