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

icaRIntercellular adhesion regulator; Represses transcription of the icaADBC operon necessary for biofilm production. (185 aa)    
Predicted Functional Partners:
icaA
Intercellular adhesion protein A; 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.
     
 0.957
icaD
Intercellular adhesion protein D; 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.
     
 0.956
icaB
Intercellular adhesion protein B; Catalyzes the N-deacetylation of poly-beta-1,6-N-acetyl-D- glucosamine (PNAG, also referred to as PIA), a biofilm adhesin polysaccharide. In fact, the IcaB deacetylase converts 15 to 20% of the GlcNAc residues of PNAG to glucosamine. 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. Deacetylation of the polymer is also essential for key virulence mechanisms of S.epidermidis, namely biof [...]

icaC
Intercellular adhesion protein C; 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 (By similarity). Is essential for long-chain PIA synthesis.

luxS
Autoinducer-2 production protein LuxS; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family.

sarA
Staphylococcal accessory regulator A; Identified by similarity to EGAD:42500; match to protein family HMM TIGR01889.
      
 0.849
atlE
Bifunctional autolysin; Endohydrolysis of the di-N-acetylchitobiosyl unit in high- mannose glycopeptides and glycoproteins containing the -[(Man)5(GlcNAc)2]-Asn structure. One N-acetyl-D-glucosamine residue remains attached to the protein; the rest of the oligosaccharide is released intact. Cleaves the peptidoglycan connecting the daughter cells at the end of the cell division cycle, resulting in the separation of the two newly divided cells. Acts as an autolysin in penicillin-induced lysis (By similarity); In the C-terminal section; belongs to the glycosyl hydrolase 73 family.

tcaR
Transcriptional regulator TcaR; Identified by similarity to OMNI:SA2353; match to protein family HMM PF01047.
      
 0.755
aap
Accumulation associated protein; Identified by match to protein family HMM PF00746; match to protein family HMM PF04650; match to protein family HMM TIGR01167; match to protein family HMM TIGR01168.

rsbU
Sigma factor B regulator protein; Identified by similarity to GP:1729794.
