This enzyme catalyses the C-1 methylation of cobalt-precorrin-5B in the anaerobic (early cobalt insertion) pathway of adenosylcobalamin biosynthesis. See EC 2.1.1.152, precorrin-6A synthase (deacetylating), for the C1-methyltransferase that participates in the aerobic cobalamin biosynthesis pathway.
The expected taxonomic range for this enzyme is: Bacteria, Archaea

coexpression of the cobA gene from Propionibacterium freudenreichii and the cbiA, -C, -D, -E, -T, -F, -G, -H, -J, -K, -L, and -P genes from Salmonella enterica serovar typhimurium in Escherichia coli result in the production of cobyrinic acid a,c-diamide. A cbiD deletion mutant of this strain produces 1-desmethylcobyrinic acid a,c-diamide, indicating that CbiD is involved in C-1 methylation in the anaerobic pathway to cobalamin
Genetically engineered production of 1-desmethylcobyrinic acid, 1-desmethylcobyrinic acid a,c-diamide, and cobyrinic acid a,c-diamide in Escherichia coli implies a role for CbiD in C-1 methylation in the anaerobic pathway to cobalamin
