Precorrin-8X methylmutase
In enzymology, a precorrin-8X methylmutase is an enzyme that catalyzes the chemical reaction
Hence, this enzyme has one substrate, precorrin 8X, and one product, hydrogenobyrinate.
This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring other groups. The systematic name of this enzyme class is precorrin-8X 11,12-methylmutase. Other names in common use include precorrin isomerase, hydrogenobyrinic acid-binding protein and CobH. This enzyme is part of the biosynthetic pathway to cobalamin in aerobic bacteria.As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes,,,,, and.
