Protein A is the von Willebrand factor binding protein on Staphylococcus aureus.
Endovascular infection is a highly critical complication of invasive Staphylococcus aureus disease. For colonization, staphylococci must first adhere to adhesive endovascular foci. Von Willebrand factor (vWF) is a large, multimeric glycoprotein mediating platelet adhesion at sites of endothelial damage. Earlier it was demonstrated that vWF binds to and promotes the surface adhesion of S. aureus...
متن کاملA novel von Willebrand factor binding protein expressed by Staphylococcus aureus.
When a shotgun phage-display library of Staphylococcus aureus Newman was affinity selected (panned) against recombinant von Willebrand factor (vWf), a novel von Willebrand factor binding protein (vWbp) was found. Experimental data indicate that the interaction between vWbp and vWf is very specific and mediated by a region of 26 aa residues in the C-terminal part of vWbp. vWbp has an N-terminal ...
متن کاملFactor VIII/von Willebrand factor protein. Galactose a cryptic determinant of von Willebrand factor activity.
The normal Factor VIII/von Willebrand factor protein has the ability to agglutinate or aggregate normal platelets in the presence of ristocetin (von Willebrand factor activity). Removal of greater than 95% of the sialic acid from this protein by neuraminidase did not affect the von Willebrand factor or procoagulant activity. However, oxidation of the penultimate galactose of the asialo Factor V...
متن کاملStaphylococcus aureus protein A binding to von Willebrand factor A1 domain is mediated by conserved IgG binding regions.
Protein A (Spa) is a surface-associated protein of Staphylococcus aureus best known for its ability to bind to the Fc region of IgG. Spa also binds strongly to the Fab region of the immunoglobulins bearing V(H)3 heavy chains and to von Willebrand factor (vWF). Previous studies have suggested that the protein A-vWF interaction is important in S. aureus adherence to platelets under conditions of ...
متن کاملInteraction of von Willebrand factor with Staphylococcus aureus.
Intravascular infection due to Staphylococcus aureus requires colonization of subendothelium in the presence of shear forces. von Willebrand factor (VWF) is a large multimeric glycoprotein playing a key role in platelet adhesion to subendothelium. To determine whether VWF may also play a role in adhesion of S. aureus to endovascular sites, binding of VWF to S. aureus and adhesion of S. aureus t...
