Csga formation
WebAlthough CsgA is prone to aggregation and forms amyloid fibers in vitro (2, 27), the formation of curli fibers in vivo is nucleated by CsgB (28–30). CsgC exists in periplasm and is an effective inhibitor of CsgA polymerization, suppressing fibrilization at substoichiometric ratios as low as 1:500 (CsgC:CsgA) ( 31 ), and perhaps preventing ... WebFeb 22, 2024 · In the early stage of biofilm formation in E. coli, CsgD is induced by multiple transcription factors such as IHF, which is a nucleoid protein, and OmpR, a transcription factor, and activates curli fimbriae (constituent subunits CsgA and CsgB) formation [21,23,29]. Our data suggested that YccT was simultaneously induced with curli fimbriae …
