EC 2.1.1.289

Accepted name: cobalt-precorrin-7 (C5)-methyltransferase

Reaction: cobalt-precorrin-7 + S-adenosyl-L-methionine = cobalt-precorrin-8 + S-adenosyl-L-homocysteine

Other name(s): CbiE

Systematic name: S-adenosyl-L-methionine:precorrin-7 C5-methyltransferase

Comments: This enzyme catalyses the methylation at C-5 of cobalt-precorrin-7, a step in the anaerobic (early cobalt insertion) adenosylcobalamin biosynthesis pathway.
