Betaine homocysteine S-methyltransferase (BHMT) is a catalytic enzyme containing metal zinc, belonging to the transferase family. It is particularly involved in the metabolism of glycine, serine, threonine, and methionine by transferring methyl groups containing one carbon group. It has been determined that this enzyme can bind to microtubule proteins and link to autophagosomes. Research has shown that this enzyme can regulate the expression of Apolipoprotein B, leading to an increase in related lipoprotein levels. In addition, BHTM is an important Hcy methyltransferase in the body, playing a crucial role in regulating plasma Hcy concentration. Our company's BHMT is a genetically modified product, free from animal derived viruses, with high purity and good activity. The specific reactions catalyzed by BHMT are as follows: Betaine+L-homocysteine=Dimethylglycine+L-methionine
