Pilus assembly protein
WebFurther study on the adsorption receptor of phage BUCT700 revealed that BUCT700 can adsorb bacteria using Type IV fimbrial biogenesis protein PilX. PilX highly conserved in bacterial genome was implicated as key promoters of pilus assembly on the cell surface and played a key role in pathogenesis in a variety of bacterial species . WebApr 5, 2013 · In current models of pilus function, pilins are first secreted into the inner membrane by the Sec system ( 19, 20) and then polymerized by the assembly system through the action of a hexameric ATPase (PilB in P. aeruginosa ), which undergoes large conformational changes upon ATP hydrolysis ( 21, 22 ).

WebSpecificity is mediated by binding of the ES to TcpB, a minor pilin that primes pilus assembly and forms a trimer at the pilus tip. Finally, the ES is proteolyzed from the mature TcpF protein upon secretion. Together, these results provide a mechanism for delivery of TcpF across the outer membrane and release into the extracellular space.
