Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage

Chains	Enzyme Name	Description	Catalytic Residues
A	precorrin-8X methylmutase M-CSA #193	Precorrin-8x methyl mutase (CobH) catalyses the migration of a methyl group attached to C-11 of the substrate, precorrin-8x, to the adjacent C-12 to give the product hydrogenobyrinic acid (HBA).This is a step in the aerobic biosynthesis of the corrin macrocycle of vitamin B12.
