Betaine-homocysteine methyltransferase
Homocysteine, a potentially cytotoxic amino acid, is remethylated to methionine in two ways:
By Methionine Synthase (MTR):homocysteine + 5-methyltetrahydrofolate ---> methionine + Dihydrofolate
By BHMT:homocysteine + betaine ---> methionine + dimethylglycine
BHMT is expressed most predominantly in the liver and kidney [cite journal |author=Sunden SL, Renduchintala MS, Park EI, Miklasz SD, Garrow TA |title=Betaine-homocysteine methyltransferase expression in porcine and human tissues and chromosomal localization of the human gene |journal=Arch.
