Definition: A methyltransferase that catalyzes the reaction of S-adenosyl-L-methionine and phenylethanolamine to yield S-adenosyl-L-homocysteine and N-methylphenylethanolamine. It can act on various phenylethanolamines and converts norepinephrine into epinephrine. (From Enzyme Nomenclature, 1992) EC 2.1.1.28.
Other names Phenethanolamine N-Methyltransferase; Phenylethanolamine N Methyltransferase; Phenethanolamine N Methyltransferase; Norepinephrine N Methyltransferase; Noradrenaline N Methyltransferase; Noradrenalin N Methyltransferase; Methyltransferase, Norepinephrine; Norepinephrine N-Methyltransferase; Norepinephrine Methyltransferase; Noradrenaline N-Methyltransferase; Noradrenalin N-Methyltransferase
