Cobalt-precorrin-5B (C1)-methyltransferase (EC 2.1.1.195), cobalt-precorrin-6A synthase, CbiD (gene)) is an enzyme with systematic name S-adenosyl-L-methionine:cobalt-precorrin-5B (C1)-methyltransferase.[1][2] This enzyme catalyses the following chemical reaction

cobalt-precorrin-5B + S-adenosyl-L-methionine [math]\displaystyle{ \rightleftharpoons }[/math] cobalt-precorrin-6A + S-adenosyl-L-homocysteine

This enzyme catalyses the C-1 methylation of cobalt-precorrin-5B in the anaerobic pathway[3] of adenosylcobalamin biosynthesis in bacteria such as Salmonella typhimurium, Bacillus megaterium, and Propionibacterium freudenreichii subsp. shermanii.
