Collagen-binding proteins from enterococcal bacteria
MetadataShow full item record
A collagen-binding MSCRAMM entitled Ace from enterococcal bacteria is provided which was homologous to the ligand-binding region of Cna, the collagen-binding MSCRAMM from Staphylococcus aureus, and which can be utilized to inhibit adhesion of enterococcal bacteria to extracellular matrix proteins. The N-terminal region of Ace contained a region (residues 174-319), or A domain, contains several 47-residue tandem repeat units between the collagen-binding site and cell wall-associated regions. The Ace protein can be utilized in methods of preventing and/or treating enterococcal infection, and in addition, antibodies raised against Ace, or its A domain, can be used to effectively inhibit the adhesion of enterococcal cells to a collagen substrate.
