Predicted to enable S-methyltransferase activity and zinc ion binding activity. Predicted to be involved in L-methionine salvage; S-adenosylmethionine metabolic process; and S-methylmethionine metabolic process. Predicted to act upstream of or within methionine biosynthetic process. Is expressed in several structures, including alimentary system and liver. Orthologous to human BHMT2 (betaine--homocysteine S-methyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
