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

nhaRLysr family transcriptional regulator, transcriptional activator of nhaa; Plays a role in the positive regulation of NhaA (301 aa)    
Predicted Functional Partners:
nhaA
Na+:h+ antiporter, nhaa family; Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 2 H(+) per Na(+). Can mediate sodium uptake when a transmembrane pH gradient is applied. Active at alkaline pH. Activity is strongly down-regulated below pH 6.5
  
  
 0.984
pgaA
Exports the biofilm adhesin polysaccharide poly-beta-1,6-N- acetyl-D-glucosamine (PGA) across the outer membrane. The PGA transported seems to be partially N-deacetylated since N-deacetylation of PGA by PgaB is needed for PGA export through the PgaA porin
      
 0.822
ribF
Bifunctional riboflavin kinase/fmn adenylyltransferase; Riboflavin biosynthesis protein RibF; Putative regulator; Not classified
 
      0.761
nhaB
Na+:h+ antiporter, nhab family; Na(+)/H(+) antiporter that extrudes sodium in exchange for external protons. Catalyzes the exchange of 3 H(+) per 2 Na(+). Has a high affinity for sodium, but can also transport lithium. Activity is weakly pH-dependent. Essential for regulation of intracellular pH under alkaline conditions
  
   
 0.721
csrA
A key translational regulator that binds mRNA to regulate translation initiation and/or mRNA stability, initially identified for its effects on central carbon metabolism . Mediates global changes in gene expression, shifting from rapid growth to stress survival by linking envelope stress, the stringent response and the catabolite repression systems . Binds to the 5'-UTR of mRNA to repress or activate translation; 2 binding sites on the homodimer can bridge 2 sites within target RNA (By similarity). Exerts reciprocal effects on enzymes of gluconeogenesis and glycogen biosynthesis versus [...]
      
 0.664
osmC
Lipoyl-dependent cys-based peroxidase, hydroperoxide resistance; Preferentially metabolizes organic hydroperoxides over inorganic hydrogen peroxide
      
 0.592
yjjJ
Putative protein kinase; Toxic when overexpressed in E.coli, leading to long filamentous cells. The toxic effect is neutralized by non-cognate antitoxin HipB . Does not seem to inhibit DNA, RNA or protein synthesis, and unlike paralogous toxin HipA its toxic activity is not counteracted by overexpression of GltX . Binds DNA . Might be a protein kinase (By similarity)
      
 0.582
rpoS
Rna polymerase nonessential primary-like sigma factor; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response. Controls, positively or negatively, the expression of several hundred genes, which are mainly involved in metabolism, transport, regulation and stress management
  
   
 0.548
gadX
Arac family transcriptional regulator, glutamate-dependent acid resistance regulator; Positively regulates the expression of about fifteen genes involved in acid resistance such as gadA, gadB and gadC. Depending on the conditions (growth phase and medium), can repress gadW
   
  
 0.506
clpS
Specificity factor for clpa-clpp chaperone-protease complex; Involved in the modulation of the specificity of the ClpAP- mediated ATP-dependent protein degradation
