Elastin binding protein; Promotes binding of soluble elastin peptides and tropoelastin to S.aureus cells although it is not able to promote bacterial adherence to immobilized elastin and, therefore, is not a microbial surface component recognizing adhesive matrix molecule (MSCRAMM). May be involved in sensing the environment or in nutrient transport, since its loss caused a growth defect.

Conserved hypothetical protein; Mediates binding to human platelets, possibly through a receptor-ligand interaction. Probably associated with virulence in endovascular infection. Plays a positive role in biofilm formation, possibly by self-association via the non-repeat region (NRR or binding region, BR). Binds to and plays a role in human lung epithelial cell invasion via the L-lectin module of its NRR domain; N-acetylneuraminic acid (Neu5Ac) inhibits binding. Treatment of host cells with neuraminidase decreases adherence of S.aureus cells, suggesting SraP recognizes a host terminal N [...]

Conserved hypothetical protein; Required for polymorphic O-glycosylation of the serine-rich repeat protein in this bacteria. A stabilizing protein that is part of the accessory SecA2/SecY2 system specifically required to export serine-rich repeat cell wall proteins usually encoded upstream in the same operon. The GtfA-GtfB complex adds GlcNAc from UDP-GlcNAc to the substrate protein, attaching the first sugar residue. Stabilizes the glycosylation activity of GtfA. Has no N-acetylglucosaminyl transferase activity on its own.

Conserved hypothetical protein.

Clumping factor; Cell surface-associated protein implicated in virulence. Promotes bacterial attachment exclusively to the gamma-chain of human fibrinogen. Induces formation of bacterial clumps, which diminish the ability of group IIA phospholipase A2 to cause bacterial phospholipid hydrolysis and killing. Significantly decreases macrophage phagocytosis possibly thanks to the clumps, clumped bacteria being too large to be phagocytosed. Dominant factor responsible for human platelet aggregation, which may be an important mechanism for initiating infective endocarditis. Enhances spleen c [...]

Conserved hypothetical protein.

sdrC protein, putative; Cell surface-associated calcium-binding protein which plays an important role in adhesion and pathogenesis. Mediates interactions with components of the extracellular matrix such as host NRXN1 to promote bacterial adhesion.
