Alpha-ribazole phosphatase

The primary biochemical reaction catalyzed by the adenosylcobalamin-5'-phosphate phosphatase (formerly alpha-ribazole phosphatase) () enzyme is
This enzyme can also catalyze the following reaction in vitro, however it is not the biologically relevant reaction
Thus, the two substrates of this enzyme are adenosylcobalamin-5'-phosphate and H2O, whereas its two products are adenosylcobalamin and phosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is adenosylcobalamin-5'-phosphate phosphohydrolase. This enzyme is also called CobC. This enzyme is part of the biosynthetic pathway to cobalamin (vitamin B12) in bacteria.
