Pilus tip adhesin Cpa

UniProtKB accession:  S5FV19

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the pilus tip. Can bind covalently, via its two reactive thioester bonds, to molecular targets from host cell surface and can thus mediate adhesion of the streptococcal pili to host cells. Lysine side chains or a carbohydrate with a free amine group might be candidates for Cpa binding. In vitro, can covalently bind to spermidine, but it is unlikely that spermidine is the natural target of Cpa.
