产品内容
本酶催化的反应为(1) 2 S-Adenosyl-L-Methionine + A Menaquinone + Reduced Flavodoxin = S-Adenosyl-L-Homocysteine + L-Methionine + 5'-Deoxyadenosine + An 8-Methylmenaquinone + Oxidized Flavodoxin;;(2) 2 S-Adenosyl-L-Methionine + A 2-Demethylmenaquinone + Reduced Flavodoxin = S-Adenosyl-L-Homocysteine + L-Methionine + 5'-Deoxyadenosine + A 2-Demethyl-8-Methylmenaquinone + Oxidized Flavodoxin，系统名称为S-Adenosyl-L-Methionine:menaquinone C8-Methyltransferase，该酶存在于广泛的细菌和古菌中，是一种自由基 SAM（AdoMet）酶，利用两分子 S-腺苷-L-甲硫氨酸——一分子作为甲基供体，另一分子用于产生推动反应进行的 5'-脱氧腺苷自由基。
