| Specific Function
| Responsible for autoagglutination, and for adhesion to abiotic and biotic surfaces such as polystyrene (PS), type I collagen, polypropylene (PP), polyvinylchloride (PVC), glass and stainless steel (SS). Adhesion is much stronger than that mediated by Yersinia YadA in a comparative assay. Confers autoagglutination and binding to PS, type I collagen, PP, PVC, glass and SS upon expression in Acinetobacter baylyi strain ADP1 (PubMed:23155410). Involved in rapid, irreversible adherence to polyurethane (PubMed:17090933). Forms an unusual biofilm (PubMed:31972092). An extended, surface exposed fiber binds to quartz crystals, PS and glass. It can be removed by washing in distilled water (PubMed:27305955, PubMed:28720107). |
