<p>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 (this domain) and chaperone binding C terminus. The carbohydrate-binding domain interacts with the receptor glycan [<cite idref="PUB00008963"/>, <cite idref="PUB00008964"/>].</p> PapG, carbohydrate-binding
