Protein

Betaine--homocysteine S-methyltransferase 1

Gene

bhmt

Organism
Xenopus tropicalis (Western clawed frog) (Silurana tropicalis)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

Trimethylammonioacetate + L-homocysteine = dimethylglycine + L-methionine.

Cofactori

Zn2+By similarityNote: Binds 1 zinc ion per subunit.By similarity
