Crystal structure of Staphylococcus aureus clumping factor A in complex with fibrinogen derived peptide and uses thereof
MetadataShow full item record
The present invention provides a method for determining the structure of a microbial surface components recognizing adhesive matrix molecule in complex with fibrinogen, by providing a ClfA complexed with a fibrinogen gamma-peptide; determining a ClfA binding region of the fibrinogen gamma-peptide; determining one or more critical amino acid residues in the ClfA binding region of a native fibrinogen gamma-peptide that is critical for a ClfA:fibrinogen gamma-peptide interaction; determining one or more amino acid residues of the ClfA that binds to the ClfA binding region of the native fibrinogen gamma-peptide; modeling the structure of the ClfA binding region; determining the structure of the ClfA in complex with the :fibrinogen gamma-peptide interaction; and identifying one or more potential agent(s) that inhibit the ClfA:fibrinogen gamma-peptide interaction without affecting binding of other proteins to the fibrinogen gamma-peptide.
