Description
PapG, the adhesin of the P-pili, is situated at the tip and is only a minor component of the whole pilus structure. 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 [PMID: 11454740, PMID: 11440716].
