Metabolite Identification
Common NameAquacobalamin
DescriptionAquacobalamin is one of the major forms of vitamin B(12) isolated from mammalian cells. Aquacobalamin and the thiolate forms of glutathione are the precursors of glutathionylcobalamin (GSCbl, a precursor to the formation of the two coenzyme forms of vitamin B(12), adenosylcobalamin and methylcobalamin) in mammalian cells. Under biological conditions the formation of GSCbl from aquacobalamin and glutathione is essentially irreversible; upon entering cells, any free (protein-unbound) aquacobalamin could be rapidly and irreversibly converted to GSCbl. (PMID: 15476387 ). Aquacobalamin is reduced to cob(II)alamin by Methionine synthase reductse (MSR) in the presence of NADPH, and this reduction leads to stimulation of the conversion of apomethionine synthase and aquacobalamin to methionine synthase holoenzyme. MSR serves as a special chaperone for human methionine synthase and as an aquacobalamin reductase, rather than acting solely in the reductive activation of methionine synthase. (PMID: 16769880 ).
