Proline isomerization modulates the bacterial IsdB/hemoglobin interaction: an atomic force spectroscopy study by Francesca Pancrazi, Omar De Bei, Francesco Lavecchia di Tocco, Marialaura Marchetti, Barbara Campanini, Salvatore Cannistraro, Stefano Bettati, Anna Rita Bizzarri

“…Abstract Iron surface determinant B (IsdB), a Staphylococcus aureus (SA) surface protein involved in both heme iron acquisition from host hemoglobin (Hb) and bacterial adhesion, is a proven virulence factor that can be targeted for the design of antibacterial molecules or vaccines. Recent single-molecule experiments on IsdB interaction with cell adhesion factors revealed an increase of the complex lifetime upon applying a stronger force (catch bond); this was suggested to favor host invasion under shear stress. …”
