描述
Adenosyl cobinamide phosphate, a known intermediate of the de novo biosynthetic pathway, is involved in Porphyrin and chlorophyll metabolism.In Salmonella typhimurium LT2, under anaerobic conditions, CobU (EC 2.7.7.62 and EC 2.7.1.156), CobT (EC 2.4.2.21), CobC (EC 3.1.3.73) and CobS (EC 2.7.8.26) catalyse reactions in the nucleotide loop
assembly pathway, which convert adenosylcobinamide (AdoCbi) into
adenosylcobalamin (AdoCbl). CobT and CobC are involved in 5,6-dimethylbenzimidazole activation whereby
5,6-dimethylbenzimidazole is converted to its riboside,
alpha-ribazole. The second branch of the nuclotide loop assembly
pathway is the cobinamide (Cbi) activation branch where AdoCbi or
adenosylcobinamide-phosphate is converted to the activated
intermediate AdoCbi-GDP by the bifunctional enzyme Cob U. The final
step in adenosylcobalamin biosynthesis is the condensation of
AdoCbi-GDP with alpha-ribazole, which is catalysed by EC 2.7.8.26,
cobalamin synthase (CobS), to yield adenosylcobalamin. [HMDB]
