Allosteric Regulation of Fibronectin/α5β1 Interaction by Fibronectin-Binding MSCRAMMs
Adherence of microbes to host tissues is a hallmark of infectious disease and is often mediated by a class of adhesins termed MSCRAMMs (Microbial Surface Components Recognizing Adhesive Matrix Molecules). Numerous pathogens express MSCRAMMs that specifically bind the heterodimeric human glycoprotein fibronectin (Fn). In addition to roles in adhesion, Fn-binding MSCRAMMs exploit physiological Fn...
متن کاملCrystal structures of fibronectin-binding sites from Staphylococcus aureus FnBPA in complex with fibronectin domains.
Staphylococcus aureus can adhere to and invade endothelial cells by binding to the human protein fibronectin (Fn). FnBPA and FnBPB, cell wall-attached proteins from S. aureus, have multiple, intrinsically disordered, high-affinity binding repeats (FnBRs) for Fn. Here, 30 years after the first report of S. aureus/Fn interactions, we present four crystal structures that together comprise the stru...
متن کاملInteraction of Staphylococcus aureus fibronectin-binding protein with fibronectin: affinity, stoichiometry, and modular requirements.
The repetitive D1, D2, and D3 elements of Staphylococcus aureus fibronectin-binding protein FnBPA each bind the N-terminal 29-kDa fragment (N29) of fibronectin with low micromolar dissociation constants (Kd), but in tandem they compose a high affinity domain, D1-3. An additional seven Fn-binding segments have been predicted in FnBPA in a region N-terminal of the D-repeats (Schwarz-Linek, U., We...
متن کاملModulation of haptotactic migration of metastatic melanoma cells by the interaction between heparin and heparin-binding domain of fibronectin.
We utilized recombinant fibronectin polypeptides with cell-binding domain and heparin-binding domains (referred to as C-274 and H-271, respectively) and their fusion polypeptide (CH-271) to examine the role of sulfated polysaccharide heparin and/or the functional domains of fibronectin in modulating tumor cell behavior. Both C-274 and CH-271 polypeptides with cell-binding domains promoted the a...
متن کاملCirculating fibronectin and fibronectin receptor in children with pertussis.
AIM To determine concentrations of fibronectin and fibronectin receptor in children with pertussis. METHODS Concentrations of circulating fibronectin and serum fibronectin receptor were detected in eight children affected by pertussis, eight children with acute upper or lower respiratory tract infections, and in 14 healthy control children. The single radial immunodiffusion technique and a so...
