Rate-limiting Description

"Conversion of PE to PME and PME to PC in the presence of S-adenosyl-L-methionine (SAM) are catalyzed by two phospholipid N-methyltransferases, PMT I and PMT II, of which PMT I is the rate limiting enzyme." (8207329)

"The enzymes tyrosine hydroxylase (TH) and phenylethanolamine N-methyltransferase (PNMT) catalyze the rate-limiting step in the catecholamine pathway and production of epinephrine, respectively." (9380436)
