Abstract
Like amino acids, the sugars glucose and the nonmetabolizable 2-deoxyglucose caused a turnover of methyl groups on the methyl-accepting chemotaxis proteins. These sugars also caused methanol formation on addition. Thus, in contrast to chemotaxis in Escherichia coli, taxis to phosphotransferase sugars by Bacillus subtilis utilizes the methyl-accepting chemotaxis proteins.
摘要
与氨基酸一样，葡萄糖和不可代谢的2-脱氧葡萄糖等糖类会导致甲基接受趋化蛋白上的甲基发生周转。这些糖类在添加时也会导致甲醇形成。因此，与大肠杆菌中的趋化作用不同，枯草芽孢杆菌对磷酸转移酶糖类的趋化作用利用了甲基接受趋化蛋白。
