Precorrin-8X methylmutase

In enzymology, a precorrin-8X methylmutase (EC number|5.4.1.2) is an enzyme that catalyzes the chemical reaction

:precorrin-8X $ightleftharpoons$ hydrogenobyrinate

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 acyl groups. The systematic name of this enzyme class is precorrin-8X 11,12-methylmutase. Other names in common use include precorrin isomerase, and hydrogenobyrinic acid-binding protein. This enzyme participates in porphyrin and chlorophyll metabolism.

tructural studies

As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes PDB link|1F2V, PDB link|1I1H, PDB link|1OU0, PDB link|1V9C, PDB link|2AFR, and PDB link|2AFV.
