Cobalt-precorrin-5B (C1)-methyltransferase (EC 2.1.1.195 cobalt-precorrin-6A synthase CbiD (gene)) is an enzyme with system name S-adenosyl-L-methionine:cobalt-precorrin-5B (C1)-methyltransferase. This enzyme catalyses the following chemical reaction cobalt-precorrin-5B + S-adenosyl-L-methionine cobalt-precorrin-6A + S-adenosyl-L-homocysteineThis enzyme catalyses the C-1 methylation of cobalt-precorrin-5B in the anaerobic pathway of adenosylcobalamin biosynthesis.
