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.

icaAIntercellular 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). (412 aa)    
Predicted Functional Partners:
icaD
Conserved hypothetical protein; Necessary for the synthesis of poly-beta-1,6-N-acetyl-D- glucosamine (PNAG, also referred to as PIA), a biofilm adhesin polysaccharide. Is required for full IcaA N- acetylglucosaminyltransferase activity (By similarity).
    
 0.996
icaB
icaB protein, putative; Catalyzes the N-deacetylation of poly-beta-1,6-N-acetyl-D- glucosamine (PNAG, also referred to as PIA), a biofilm adhesin polysaccharide. N-deacetylation is crucial for attachment of the polysaccharide to the bacterial cell surface; it leads to the introduction of positive charges in the otherwise neutral PIA polymer, allowing electrostatic interactions (By similarity).
 
  
 0.980
icaR
Ica operon transcriptional regulator IcaR, putative; Represses transcription of the icaADBC operon necessary for biofilm production.
     
 0.967
icaC
Intercellular adhesion protein C, putative; Presumably involved in the export of the biofilm adhesin polysaccharide poly-beta-1,6-N-acetyl-D-glucosamine (PNAG, also referred to as PIA) across the cell membrane.

ABD30797.1
Conserved hypothetical protein.

eno
Enolase; Catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis; Belongs to the enolase family.
   
 
 0.819
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.

sarA
Staphylococcal accessory regulator T, putative; Global regulator with both positive and negative effects that controls expression of several virulence factors and biofilm formation process in a cell density-dependent manner. In a strain-dependent manner plays a role in multidrug resistance mechanism. Is required for transcription of primary transcripts RNAII and RNAIII generated by agr (virulence accessory gene regulator) locus. Acts as a transcriptional activator of the genes encoding, among others, for fibronectin binding proteins (fnbA and fnbB), hemolysins (hla, hld, hlgB and hlgC) [...]
   
  
 0.710
fnbA
Fibronectin-binding protein precursor, putative; Possesses multiple, substituting fibronectin (Fn) binding regions, each capable of conferring adherence to both soluble and immobilized forms of Fn. This confers to S.aureus the ability to invade endothelial cells both in vivo and in vitro, without requiring additional factors, although in a slow and inefficient way through actin rearrangements in host cells. This invasion process is mediated by integrin alpha-5/beta-1. Promotes bacterial attachment to both soluble and immobilized forms of fibrinogen (Fg) by means of a unique binding sit [...]
