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

dpsStarvation-inducible DNA-binding protein; Expression of DPS is induced by oxidative or nutritional stress, including metal ion starvation; Belongs to the Dps family. (175 aa)    
Predicted Functional Partners:
clpS
ATP-dependent Clp protease adaptor protein clpS; Involved in the modulation of the specificity of the ClpAP- mediated ATP-dependent protein degradation; Belongs to the ClpS family.
   
 
 0.853
ahpC
Alkyl hydroperoxide reductase C; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
  
  
 0.766
nifJ1
Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase, Pyruvate + CoA + oxidized flavodoxin = acetyl-CoA + CO2 + reduced flavodoxin.
    
 
 0.744
nifJ2
Pyruvate:ferredoxin (Flavodoxin) oxidoreductase.
   
 
 0.677
hpf
Ribosomal S30AE, sigma 54 modulation protein; Required for dimerization of active 70S ribosomes into 100S ribosomes in stationary phase; 100S ribosomes are translationally inactive and sometimes present during exponential growth.
   
    0.618
CBL55806.1
6 Protein of unknown function, without similarity to other proteins; Belongs to the UPF0337 (CsbD) family.
  
  
 0.607
katA
Catalase; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide, 2 H2O2 = O2 + 2 H2O, Heme group, cofactor NADPH, Homotetramer, Cytoplasm, catalase family.
  
  
 0.545
usp
The universal stress protein UspA is a small cytoplasmic bacterial protein whose expression is enhanced when the cell is exposed to stress agents.
  
  
 0.529
sodA
Iron/Manganese superoxide dismutase (Superoxide dismutase [Mn/Fe]) (SODM); Destroys radicals which are normally produced within the cells and which are toxic to biological systems. Belongs to the iron/manganese superoxide dismutase family.
  
  
 0.478
ahpF
Alkyl hydroperoxide reductase subunit F.
  
  
 0.473
