The effects of selenite, selenocystine, and selenomethionine in a defined growth medium on formic dehydrogenase biosynthesis in aerobically and anaerobically grown Escherichia coli have been studied. Sucrose gradient centrifugation of a partially purified enzyme demonstrated a coincidence of (75)Se incorporation and formic dehydrogenase activity.
已研究了亚硒酸盐、硒代胱氨酸和硒代蛋氨酸在特定生长培养基中对需氧和厌氧培养的大肠杆菌甲酸脱氢酶生物合成的影响。对部分纯化的酶进行蔗糖梯度离心,结果表明(75)Se掺入与甲酸脱氢酶活性一致。
