口腔病原体变形链球菌的高亲和力蔗糖摄取是由磷酸烯醇丙酮酸依赖的磷酸转移酶系统介导的。在本报告中，我们提供了证据，证明变形链球菌GS-5中的低亲和力蔗糖磷酸转移酶系统实际上是一个高亲和力海藻糖摄取系统，它也识别蔗糖作为底物。
High-affinity sucrose uptake in the oral pathogen Streptococcus mutans is mediated by the phosphoenolpyruvate-dependent phosphotransferase system. In this report, we provide evidence that a lower-affinity sucrose phosphotransferase system in S. mutans GS-5, previously described by others, is in fact a high-affinity trehalose uptake system that also recognizes sucrose as a substrate.
