Collagen binding to Staphylococcus aureus.
Staphylococcus aureus can bind soluble collagen in a specific, saturable manner. We have previously shown that some variability exists in the degree of collagen binding between different strains of heat-killed, formaldehyde-fixed S. aureus which are commercially available as immunologic reagents. The present study demonstrates that live S. aureus of the Cowan 1 strain binds amounts of collagen ...
متن کاملFactors affecting the collagen binding capacity of Staphylococcus aureus.
To determine whether the ability of Staphylococcus aureus to bind collagen involves an adhesin other than the collagen adhesin encoded by cna, we examined the collagen binding capacity (CBC) of 32 strains of S. aureus. With only two exceptions, a high CBC corresponded with the presence of cna. Both exceptions involved cna-positive strains with a low CBC. The first was a single strain (ACH5) tha...
متن کاملMechanism of activation of human basophils by Staphylococcus aureus Cowan 1.
We investigated the capacity of Staphylococcus aureus Cowan 1 and S. aureus Wood 46 to induce histamine release from human basophils in vitro. S. aureus Cowan 1 (10(5) to 10(7)/ml), which synthesizes protein A (Staph A), stimulated the release of histamine from basophils, whereas S. aureus Wood 46 (10(5) to 2 X 10(7)/ml), which does not synthesize Staph A, did not induce histamine secretion. So...
متن کاملA 'Collagen Hug' model for Staphylococcus aureus CNA binding to collagen.
The structural basis for the association of eukaryotic and prokaryotic protein receptors and their triple-helical collagen ligand remains poorly understood. Here, we present the crystal structures of a high affinity subsegment of the Staphylococcus aureus collagen-binding CNA as an apo-protein and in complex with a synthetic collagen-like triple helical peptide. The apo-protein structure is com...
متن کاملBinding of elastin to Staphylococcus aureus.
Many pathogenic bacteria specifically bind to components of the extracellular matrix. In this study, we report the specific association of Staphylococcus aureus with elastin, a major structural component of elastic tissue. Competition assays in which the binding of radiolabeled tropoelastin was inhibited by excess unlabeled elastin peptides, but not by other proteins, established the specificit...
