FimD/PapC N-terminal domain-containing protein

The PapC N-terminal domain is a structural domain found at the N-terminus of the E. coli PapC protein. Pili are assembled using the chaperone usher system. In E.coli this is composed of the chaperone PapD and the usher PapC. This domain represents the N-terminal domain from PapC and its homologues. This domain is involved in substrate binding [1].

FimD/PapC C-terminal domain-containing protein

The PapC C-terminal domain is a structural domain found at the C-terminus of the E. coli PapC protein. Pili are assembled using the chaperone usher system. In E.coli this is composed of the chaperone PapD and the usher PapC. This domain represents the C-terminal domain from PapC and its homologues. This domain has a beta-sandwich structure similar to the plug domain of PapC [1]. [1]. 20118254. Structural homology between the C-terminal domain of the PapC usher and its plug.

fimbria/pilus outer membrane usher protein

In Gram-negative bacteria the biogenesis of fimbriae (or pili) requires a two- component assembly and transport system which is composed of a periplasmic chaperone and an outer membrane protein which has been termed a molecular 'usher' [1-3]. The usher protein is rather large (from 86 to 100 Kd) and seems to be mainly composed of membrane-spanning beta-sheets, a structure reminiscent of porins. Although the degree of sequence similarity of these proteins is not very high they share a number of characteristics. One of these is the presence of two pairs of cysteines, the first one located in the N-terminal part and the second at the C-terminal extremity that are probably involved in disulphide bonds. The best conserved region is located in the central part of these proteins [4-5]. [1]. 7909802. Chaperone-assisted self-assembly of pili independent of cellular energy.
