STRING protein interaction network
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 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
protein homology
Your Input:
Gene Fusion
rrrQQin prophage; putative lysozyme; Essential for lysis of bacterial cell wall, by showing cell wall hydrolyzing activity (177 aa)    
Predicted Functional Partners:
Prophage lysis protein S homolog EssQ; Phage or Prophage Related; Belongs to the lambda phage S protein family
Qin prophage; protein ydfr; Uncharacterized protein YdfR; Phage or Prophage Related
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
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
Periplasmic inhibitor of g-type lysozyme; Inhibits activity of g-type lysozyme, which confers increased lysozyme tolerance to the bacterium
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
Putative c40 clan peptidase lipoprotein; Probable endopeptidase NlpC; Lipoprotein
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
Prolipoprotein signal peptidase (signal peptidase ii); This protein specifically catalyzes the removal of signal peptides from prolipoproteins
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 [...]
