S-Adenosyl L-methionine |29908-03-0
Ibisobanuro ku bicuruzwa:
S-adenosylmethionine yavumbuwe bwa mbere n'abahanga (Cantoni) mu 1952.
Ihindurwamo na adenosine triphosphate (ATP) na methionine mu ngirabuzimafatizo na methionine adenosyl transfert (Methionine Adenosyl Transferase), kandi iyo igize uruhare mu kwimura methyl nka coenzyme, itakaza itsinda rya methyl ikabora mu itsinda rya S-adenosyl. .
