ID 2.1.1.196 DE cobalt-precorrin-6B (C(15))-methyltransferase [decarboxylating]. AN cobalt-precorrin-6Y (C(15))-methyltransferase [decarboxylating]. CA Co-precorrin-6B + S-adenosyl-L-methionine = Co-precorrin-7 + CO2 + CA S-adenosyl-L-homocysteine. CC -!- This enzyme, which participates in the anaerobic (early cobalt CC insertion) adenosylcobalamin biosynthesis pathway, catalyzes both CC methylation at C-15 and decarboxylation of the C-12 acetate side CC chain of cobalt-precorrin-6B. CC -!- The equivalent activity in the aerobic adenosylcobalamin biosynthesis CC pathway is catalyzed by the bifunctional enzyme EC 2.1.1.132.
