S-Adenosyl L-methionine | 29908-03-0
Ingcaciso yeMveliso:
I-S-adenosylmethionine yafunyanwa kuqala ngoososayensi (Cantoni) kwi-1952.
Ihlanganiswe yi-adenosine triphosphate (ATP) kunye ne-methionine kwiiseli nge-methionine adenosyl transferase (i-Methionine Adenosyl Transferase), kwaye xa ithatha inxaxheba kwi-methyl transfer reaction njenge-coenzyme, ilahlekelwa yiqela le-methyl kwaye idibanise kwi-S-adenosyl iqela le-Histidine. .
