CC -!- FUNCTION: Catalyzes the transmethylation of nonepinephrine
CC (noradrenaline) to form epinephrine (adrenaline), using S-adenosyl-L-
CC methionine as the methyl donor (PubMed:5412063). Other substrates
CC include phenylethanolamine and octopamine (By similarity). Also
CC methylates normetanephrine (PubMed:13863458, PubMed:5412063).
