ID   2.1.1.132
DE   precorrin-6B C(5,15)-methyltransferase (decarboxylating).
AN   precorrin-6 methyltransferase.
AN   precorrin-6Y C(5,15)-methyltransferase (decarboxylating).
AN   precorrin-6Y methylase.
CA   precorrin-6B + 2 S-adenosyl-L-methionine = CO2 + 3 H(+) + precorrin-8X +
CA   2 S-adenosyl-L-homocysteine.
CC   -!- The enzyme participates in the aerobic (late cobalt insertion)
CC       adenosylcobalamin biosynthesis pathway.
CC   -!- The enzyme from the bacterium Pseudomonas denitrificans is a fusion
CC       protein with two active sites; one catalyzes the methylation at C-15
CC       followed by decarboxylation of the C-12 acetate side chain, while the
CC       other catalyzes the methylation at C-5.
CC   -!- The corresponding activities in the anaerobic adenosylcobalamin
CC       biosynthesis pathway are catalyzed by EC 2.1.1.196 and EC 2.1.1.289.
