* vhp Is a Fibrinogen-Binding Protein Related to vWbp in Staphylococcus aureus.

- Staphylococcus aureus can target a variety of tissues, causing life-threatening infections. The basis for this diversity stems from the microorganism's ability to spread in the vascular system throughout the body. To survive in blood, S. aureus coats itself with a fibrinogen (Fg)/fibrin shield. The protective shield is assembled by the coordinated actions of a number of Fg-binding bacterial proteins that manipulate the host's blood coagulation system. Several of the Fg binders appear redundant, sharing similar functional motifs. This observation led us to screen for the presence of novel proteins with significant amino acid identities to von Willebrand factor-binding protein (vWbp), a key component in the shield assembly machinery. One identified protein showed significant sequence identity with the C-terminal region of vWbp, and we consequently named it vWbp homologous protein (vhp). The vhp gene lies within a cluster of genes that encode other virulence factors in S. aureus. Although each isolate only contains one copy of the vhp gene, S. aureus has at least three distinct alleles, vhpA, B, and C, that are present in the core genome. All three vhp isoforms bind Fg with high affinity, targeting a site located in the D fragment of Fg. We further identified an ∼79 amino acid-long, conserved segment within the C-terminal region of vWbp that shares high sequence identities (54 to 67%) with the vhps and binds soluble Fg with high affinity. Further analysis of this conserved motif and the intact vhps revealed intriguing differences in the Fg binding behavior, perhaps suggesting that these proteins have similar but discrete functions in the shield assembly. IMPORTANCE The life-threatening diseases caused by multidrug-resistant Staphylococcus aureus strains are a worldwide medical problem due to treatment limitations and the lack of an effective vaccine. The ability of S. aureus to coat itself with a protective fibrinogen (Fg)/fibrin shield allows the organism to survive in blood and to disseminate and cause invasive diseases. This process represents a promising target for novel antistaphylococcal treatment strategies but is incompletely understood. S. aureus expresses a number of Fg-binding proteins. Some of these proteins have apparently redundant functions. Proteins with similar functions often share a structural or functional motif with each other. In this study, we identified a protein homologous to the C-terminal of von Willebrand factor-binding protein (vWbp), a key contributor in the Fg shield assembly that also binds Fg. Further analysis allowed us to identify a common Fg-binding motif.
