我们研究了变形链球菌6715g中依赖于磷酸烯醇式丙酮酸的磷酸转移酶系统中蔗糖和葡萄糖的酶II活性。两种完整的膜蛋白，酶IIscr和酶IIglc，分别针对其糖底物蔗糖或葡萄糖，通过它们催化特定糖的能力来鉴定：糖-磷酸交换反应。文中还介绍了这两种转运蛋白的一些性质。
We investigated phosphoenolpyruvate-dependent phosphotransferase system enzyme II activities for sucrose and glucose in Streptococcus mutans 6715g. Two integral membrane proteins, enzyme IIscr and enzyme IIglc, each specific for its sugar substrate, sucrose or glucose, were identified by their abilities to catalyze specific sugar:sugar-phosphate exchange reactions. Some of the properties of these two transport proteins are also presented.
