STRINGSTRING
STRING protein interaction network
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.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

icaBicaB 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). (290 aa)    
Predicted Functional Partners:
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).
 
 
 0.998
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).
  
  
 0.962
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.
 
  
 0.961
icaR
Ica operon transcriptional regulator IcaR, putative; Represses transcription of the icaADBC operon necessary for biofilm production.
     
 0.884
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 [...]

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 [...]

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 [...]

sdrC
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.
   
  
 0.489
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.
     
 0.481
hysA
Hyaluronate lyase; Belongs to the polysaccharide lyase 8 family.
