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].

A two-domain structure has been postulated for PapG; a carbohydrate binding N-terminus (this domain) and chaperone binding C-terminus. The carbohydrate-binding domain interacts with the receptor glycan [1,2].

A two-domain structure has been postulated for PapG; a carbohydrate binding N-terminus and chaperone binding C-terminus (this domain). The chaperone-binding domain is highly conserved, and is essential for the correct assembly of the pili structure when aided by the chaperone molecule PapD [1,2].
