Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.

srtASortase, putative; Transpeptidase that anchors surface proteins to the cell wall. Recognizes and modifies its substrate by proteolytic cleavage of a C-terminal sorting signal. Following cleavage, a covalent intermediate is formed via a thioester bond between the sortase and its substrate, which is then transferred and covalently attached to the cell wall. This sortase recognizes a Leu-Pro-x-Thr-Gly (LPXTG) motif, which is cleaved by the sortase between the threonine and glycine residues. Utilizes lipid II as the peptidoglycan substrate for the sorting reaction. Responsible for the disp [...] (206 aa)    
Predicted Functional Partners:
spa
Protein A; Plays a role in the inhibition of the host innate and adaptive immune responses. Possesses five immunoglobulin-binding domains that capture both the fragment crystallizable region (Fc region) and the Fab region (part of Ig that identifies antigen) of immunoglobulins. In turn, Staphylococcus aureus is protected from phagocytic killing via inhibition of Ig Fc region. In addition, the host elicited B-cell response is prevented due to a decrease of antibody-secreting cell proliferation that enter the bone marrow, thereby decreasing long-term antibody production. Inhibits osteoge [...]

srtB
Conserved hypothetical protein; Transpeptidase that anchors surface proteins to the cell wall (Probable). Recognizes and modifies its substrate by proteolytic cleavage of a C- terminal sorting signal. Following cleavage, a covalent intermediate is formed via a thioester bond between the sortase and its substrate, which is then transferred and covalently attached to the cell wall (Probable). This sortase recognizes an Asn-Pro-Gln- Thr-Asn (NPQTN) motif in IsdC, which is cleaved by the sortase between the threonine and aspargine residues; may only have 1 substrate in this bacterium (Pro [...]

ebpS
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.

clfA
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 [...]

birA
BirA bifunctional protein, putative; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
      
 0.666
clfB
Clumping factor B, putative; Cell surface-associated protein implicated in virulence by promoting bacterial attachment to both alpha- and beta-chains of human fibrinogen and inducing the formation of bacterial clumps. Partly responsible for mediating bacterial attachment to the highly keratinized squamous epithelial cells from the nasal cavity via an interaction with cytokeratin K10 (K10). Also promotes bacterial attachment to cultured keratinocytes, possibly through an interaction with cytokeratin K10. Binds mouse cytokeratin K10. Activates human platelet aggregation; Belongs to the s [...]

mprF
Conserved hypothetical protein; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), a major component of the bacterial membrane with a positive net charge. LPG synthesis contributes to bacterial virulence as it is involved in the resistance mechanism against cationic antimicrobial peptides (CAMP) produces by the host's immune system (defensins, cathelicidins) and by the competing microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with positively [...]

icaA
Intercellular adhesion protein A, putative; N-acetylglucosaminyltransferase that catalyzes the polymerization of single monomer units of UDP-N-acetylglucosamine to produce the linear homopolymer poly-beta-1,6-N-acetyl-D-glucosamine (PNAG, also referred to as PIA), a biofilm adhesin polysaccharide. Requires IcaD for full activity (By similarity).
