Summaries for BHMT Gene

Entrez Gene Summary for BHMT Gene

  • This gene encodes a cytosolic enzyme that catalyzes the conversion of betaine and homocysteine to dimethylglycine and methionine, respectively. Defects in this gene could lead to hyperhomocyst(e)inemia, but such a defect has not yet been observed. [provided by RefSeq, Jul 2008]

GeneCards Summary for BHMT Gene

BHMT (Betaine--Homocysteine S-Methyltransferase) is a Protein Coding gene. Diseases associated with BHMT include placental abruption and hyperhomocysteinemia. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include protein complex binding and betaine-homocysteine S-methyltransferase activity. An important paralog of this gene is BHMT2.

UniProtKB/Swiss-Prot for BHMT Gene

  • Involved in the regulation of homocysteine metabolism. Converts betaine and homocysteine to dimethylglycine and methionine, respectively. This reaction is also required for the irreversible oxidation of choline
