Study of oral biofilm associated with bacterial surface amyloid

淀粉样蛋白是一种具有特定结构的不溶性纤维蛋白。很明显，这种淀粉样蛋白与革兰氏阳性细菌的生物膜形成有关。变形链球菌具有与生物膜形成有关的淀粉样蛋白。这项研究表明SMU482和SMU574可能与变形链球菌基因中的淀粉样蛋白形成有关。SMU482与生物膜的形成有关，而SMU574与生物膜的形成无关。因此，很明显淀粉样蛋白的形成不一定与生物膜的形成有关。

Amyloid is an insoluble fiber protein involving one specific structure. It was clealy that this amyloid was associated with the biofilm formation in gram positive bacteria.Streptococcus mutans is possessing the amyloid implicated in the biofilm formation.This study showed a posssibility that SMU482 and SMU574 associated with amyloid formation in S. mutans genes. SMU482 related with the biofilm formation but SMU574 did not related with that. Therefore, it was clearly that the amyloid formation is not necessarily concerned with biofilm formation.
