Enzymes for Research, Diagnostic and Industrial Use

methionine synthase

Cat No.
Contains zinc and cobamide. The enzyme becomes inactivated occasionally during its cycle by oxidation of Co(I) to Co(II). Reactivation by reductive methylation is catalysed by the enzyme itself, with S-adenosyl-L-methionine as the methyl donor and a reducing system. For the mammalian enzyme, the reducing system involves NADPH and EC, [methionine synthase] reductase. In bacteria, the reducing agent is flavodoxin, and no further catalyst is needed (the flavodoxin is kept in the reduced state by NADPH and EC, ferredoxin-NADP+ reductase). Acts on the monoglutamate as well as the triglutamate folate, in contrast with EC, 5-methyltetrahydropteroyltriglutamate-homocysteine S-methyltransferase, which acts only on the triglutamate.
