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:
some 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

rrrQQin prophage; putative lysozyme; Essential for lysis of bacterial cell wall, by showing cell wall hydrolyzing activity (177 aa)    
Predicted Functional Partners:
essQ
Prophage lysis protein S homolog EssQ; Phage or Prophage Related; Belongs to the lambda phage S protein family
  
    0.856
ydfR
Qin prophage; protein ydfr; Uncharacterized protein YdfR; Phage or Prophage Related
       0.845
lysA
Diaminopimelate decarboxylase, plp-binding; Specifically catalyzes the decarboxylation of meso- diaminopimelate (meso-DAP) to L-lysine. Is not active against the DD- or LL-isomers of diaminopimelate
      
 0.827
nanS
9-O-acetyl-N-acetylneuraminic acid deacetylase; Probably catalyzes the hydrolysis of the 9-O-acetyl group of 9-O-acetyl-N-acetylneuraminate (Neu5,9Ac2). Is required for growth of E.coli on Neu5,9Ac2, an alternative sialic acid commonly found in mammalian host mucosal sites, in particular in the human intestine
  
   
 0.743
pliG
Periplasmic inhibitor of g-type lysozyme; Inhibits activity of g-type lysozyme, which confers increased lysozyme tolerance to the bacterium
  
     0.560
rutD
Putative reactive intermediate detoxifying aminoacrylate hydrolase; May increase the rate of spontaneous hydrolysis of aminoacrylate to malonic semialdehyde. Required to remove a toxic intermediate produce in vivo, but not in vitro in the pyrimidine nitrogen degradation
  
   
 0.537
nlpC
Putative c40 clan peptidase lipoprotein; Probable endopeptidase NlpC; Lipoprotein
     
 0.512
emtA
Membrane-bound lytic murein transglycosylase e; Murein-degrading enzyme. May play a role in recycling of muropeptides during cell elongation and/or cell division. Preferentially cleaves at a distance of more than two disaccharide units from the ends of the glycan chain. Prefers cross-linked murein in vivo
      
 0.499
lspA
Prolipoprotein signal peptidase (signal peptidase ii); This protein specifically catalyzes the removal of signal peptides from prolipoproteins
      
 0.483
recA
Dna recombination/repair protein reca; Required for homologous recombination and the bypass of mutagenic DNA lesions by the SOS response. Catalyzes ATP-driven homologous pairing and strand exchange of DNA molecules necessary for DNA recombinational repair. Catalyzes the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single- stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. The SOS response controls an apoptotic-like death (ALD) induced (in the absence of the mazE-mazF toxin-antitoxin module) in res [...]
