Streptococcus mutans NG5 failed to anchor antigen P1 to the cell surface, and such a failure could be attributed to a defective SrtA, which was made defective by a point mutation within the srtA gene. Without a functional SrtA, S. mutans NG5 was not able to perform a number of cell surface-related activities, including saliva-mediated adherence and aggregation.
变形链球菌NG5无法将抗原P1锚定到细胞表面,这种失败可能归因于分选酶A(SrtA)缺陷,该缺陷是由srtA基因内的点突变造成的。由于没有功能性的分选酶A,变形链球菌NG5无法进行许多与细胞表面相关的活动,包括唾液介导的黏附和聚集。
