IntEnz Enzyme Nomenclature
EC 2.1.1.272

Names

Accepted name:
cobalt-factor III methyltransferase
Other name:
CbiH60 (gene name)
Systematic name:
S-adenosyl-L-methionine:cobalt-factor III 17-methyltransferase (ring contracting)

Reaction

Comments:

Isolated from Bacillus megaterium. The enzyme catalyses both methylation at C-17 and ring contraction. Contains a [4Fe-4S] cluster. It can also convert cobalt-precorrin-3 to cobalt-precorrin-4. The reductant may be thioredoxin.
