39. Data suggest that Staphylococcus aureus surface protein SdrE (serine-aspartate repeat protein E) functions as a 'clamp' to capture C-terminal tail of human CFH (complement factor H) at a specific ligand-binding site/groove via unique close-dock-lock-latch mechanism and thereby sequesters CFH on surface of S. aureus for complement evasion (immune evasion). PMID: 28258151

41. Data suggest that complement factor H (CFH) attaches to surface of host cells to inhibit complement activation and amplification, preventing destruction of the host cells; SdrE (serine-aspartate repeat protein) of Staphylococcus aureus binds to CFH allowing S. aureus to mimic a host cell and reducing bacterial killing by granulocytes.
