Phosphatidylethanolamine + 3 SAM -> phosphatidylcholine + 3 SAH
-
Norepinephrine + SAM -> epinephrine + SAH
-
SAM + methyl acceptor → S-adenosylhomocysteine (SAH) + methylated acceptor
-
Substrate + SAM -> methylated metabolite + SAH
-
L-methionine + ATP → S-adenosylmethionine (SAM) + Pᵢ + PPᵢ
-
Serotonin + acetyl-CoA -> N-acetylserotonin; then + SAM -> melatonin
