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].

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].
