Adenosylcobinamide-GDP ribazoletransferase ( EC 2.7.8.26, CobS, cobalamin synthase, cobalamin-5'-phosphate synthase, cobalamin (5'-phosphate) synthase) is an enzyme with systematic name adenosylcobinamide-GDP:alpha-ribazole ribazoletransferase. [1] [2] [3] This enzyme catalyses the following chemical reaction
- (1) adenosylcobinamide-GDP + alpha-ribazole GMP + adenosylcobalamin
- (2) adenosylcobinamide-GDP + alpha-ribazole 5'-phosphate GMP + adenosylcobalamin 5'-phosphate
This enzyme is part of the biosynthetic pathway to cobalamin (vitamin B12) in bacteria.
