Thus, the two substrates of this enzyme are S-adenosyl methionine and tyramine, whereas its two products are S-adenosylhomocysteine and N-methyltyramine.
This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:tyramine N-methyltransferase. Other names in common use include DIB O-methyltransferase (3,5-diiodo-4-hydroxy-benzoic acid), S-adenosyl-methionine:tyramine N-methyltransferase, and tyramine methylpherase. This enzyme participates in tyrosine metabolism.
