| methionine synthase | 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 1.16.1.8, [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 1.18.1.2, ferredoxin-NADP+ reductase). Acts on the monoglutamate as well as the triglutamate folate, in contrast with EC 2.1.1.14, 5-methyltetrahydropteroyltriglutamate-homocysteine S-methyltransferase, which acts only on the triglutamate.

| methylenetetrahydrofolate-tRNA-(uracil54-C5)-methyltransferase (FADH2-oxidizing) | Up to 25% of the bases in mature tRNA are post-translationally modified or hypermodified. One almost universal post-translational modification is the conversion of U54 into ribothymidine in the TψC loop, and this modification is found in most species studied to date. Unlike this enzyme, which uses 5,10-methylenetetrahydrofolate and FADH2 to supply the atoms for methylation of U54, EC 2.1.1.35, tRNA (uracil54-C5)-methyltransferase, uses S-adenosyl-L-methionine.

| Native Cystathionine-β-synthase | Cystathionine-β-synthase, also known as CBS, is an enzyme (EC 4.2.1.22) that in humans is encoded by the CBS gene. CBS uses the cofactor pyridoxal-phosphate (PLP) and can be allosterically regulated by effectors such as the ubiquitous cofactor S-adenosyl-L-methionine (adoMet). This enzyme belongs to the family of lyases, to be specific, the hydro-lyases, which cleave carbon-oxygen bonds. CBS is a multidomain enzyme composed of an N-terminal enzymatic domain and two CBS domains. The CBS gene is the most common locus for mutations associated with homocystinuria. Human cbs performs a crucial step in the biosynthetic pathway of cysteine by providing a regulatory control po...nates methyl groups to a variety of substrates, e.g., neurotransmitters, proteins, and nucleic acids. in mammals, cbs is a highly regulated enzyme, which contains a heme cofactor that functions as a redox sensor, that can modulate its activity in response to changes in the redox potential. if the resting form of cbs in the cell has ferrous heme, the potential exists for activating the enzyme under oxidizing conditions by conversion to the ferric state. Group: Enzymes. Synonyms: Cystathionine-β-synthase; CBS; EC 4.2.1.22; 9023-99-8. Enzyme Commission Number: EC 4.2.1.22. CAS No. 9023-99-8. CBS. Cystathionine-β-synthase; CBS; EC 4.2.1.22; 9023-99-8.
