cobalt-precorrin-5B + S-adenosyl-L-methionine 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.
