ID   2.1.1.152
DE   Precorrin-6A synthase (deacetylating).
AN   Precorrin-6X synthase (deacetylating).
CA   S-adenosyl-L-methionine + precorrin-5 + H(2)O = S-adenosyl-L-homocysteine
CA   + precorrin-6A + acetate.
CC   -!- In the aerobic cobalamin biosythesis pathway, four enzymes are
CC       involved in the conversion of precorrin-3A to precorrin-6A.
CC   -!- The first of the four steps is carried out by EC 1.14.13.83 (CobG),
CC       yielding precorrin-3B as the product.
CC   -!- This is followed by three methylation reactions, which introduce a
CC       methyl group at C-17 (CobJ; EC 2.1.1.131), C-11 (CobM; 2.1.1.133) and
CC       C-1 (CobF; EC 2.1.1.152) of the macrocycle, giving rise to precorrin-
CC       4, precorrin-5 and precorrin-6A, respectively.
