Metabolite Identification
Common NameAquacobalamin
DescriptionAquacobalamin 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). 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.
