I-S-Adenosyl L-methionine |29908-03-0
Incazelo Yomkhiqizo:
I-S-adenosylmethionine yatholwa okokuqala ngososayensi (Cantoni) ngo-1952.
Ihlanganiswa yi-adenosine triphosphate (ATP) kanye ne-methionine kumaseli nge-methionine adenosyl transferase (Methionine Adenosyl Transferase), futhi uma ibamba iqhaza ekuphenduleni kokudluliswa kwe-methyl njenge-coenzyme, ilahlekelwa yiqembu le-methyl futhi iyihlukanise ibe yiqembu le-S-adenosyl i-Histidine. .
