Alpha-ribazole phosphatase
Template:Infobox enzyme The primary biochemical reaction catalyzed by the enzyme adenosylcobalamin/α-ribazole phosphatase (formerly α-ribazole phosphatase)[1] (EC 3.1.3.73) is
- adenosylcobalamin 5′-phosphate + H2O = coenzyme B12 + phosphate
This enzyme can also catalyze the following reaction in vitro, however it is not the biologically relevant reaction
- α-ribazole 5′-phosphate + H2O α-ribazole + phosphate
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is adenosylcobalamin/α-ribazole-5′-phosphate phosphohydrolase. This enzyme is also called CobC. It is part of the biosynthetic pathway to cobalamin (vitamin B12) in bacteria.[2][3]
