BHMT, Human

(BHMT; Betaine Homocysteine S-Methyltransferase 1; BHMT1; EC 2.1.1.5)

Betaine-homocysteine methyltransferase (BHMT) is a cytosolic enzyme that catalyzes the conversion of betaine and homocysteine to dimethylglycine and methionine, respectively. BHMT displays differential expression in a model of liver cirrhosis.

Betaine Homocysteine S-Methyltransferase Human Recombinant fused to His Tag at N-terminal produced in E. coli is a single, non-glycosylated, polypeptide chain containing 443 amino acids (21-236) and having a molecular mass of 49.2 kDa. The BHMT is purified by proprietary chromatographic techniques.

Purity > 95.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.

Source: Escherichia Coli

Physical Appearance: Sterile Filtered clear colorless solution 1 mg/ml.

Formulation: The BHMT solution contains 20mM Tris-HCl pH-7.5 and 20% glycerol.

Reaction catalysed
Trimethylammonioacetate + L-homocysteine <=> dimethylglycine + L-methionine
