Phenylethanolamine N-methyltransferase (PNMT) is an enzyme found in the adrenal medulla that converts Norepinephrine (Noradrenaline) to Epinephrine (Adrenaline).

PNMT is positively influenced by cortisol, which is produced in the adrenal cortex.

S-adenosyl-L-methionine ('SAM') is a required cofactor.[1]

PNMT converts the last step in the synthesis of epinephrine
