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

dpsAStarvation induced DNA binding protein; Protects DNA from oxidative damage by sequestering intracellular Fe(2+) ion and storing it in the form of Fe(3+) oxyhydroxide mineral. One hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl radical production by the Fenton reaction (By similarity); Belongs to the Dps family. (182 aa)    
Predicted Functional Partners:
cctA
Thermosome subunit alpha; Molecular chaperone; binds unfolded polypeptides in vitro, and has a weak ATPase activity; Belongs to the TCP-1 chaperonin family.
  
  
 0.774
sod1
Superoxide dismutase; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems.
  
  
 0.682
VNG_1446H
Hypothetical protein; Vng1446h.
   
  
 0.680
msrA
Peptide methionine sulfoxide reductase; Has an important function as a repair enzyme for proteins that have been inactivated by oxidation. Catalyzes the reversible oxidation-reduction of methionine sulfoxide in proteins to methionine.
  
  
 0.655
VNG_2508C
Conserved hypothetical protein; Vng2508c.
      
 0.653
prk
Protein kinase; Prk.
  
    0.651
prkA
Kinase anchor protein; PrkA.
  
    0.633
rnhA
Conserved hypothetical protein; Nuclease that specifically degrades the RNA of RNA-DNA hybrids; seems to act exonucleolytically on RNA/DNA hybrids. Endonucleolytically removes RNA primers from the Okazaki fragments of lagging strand synthesis on its own. Complements the temperature- sensitive phenotype of an E.coli double rnhA/rnhB (RNase H) disruption mutant.
     
 0.626
idr2
Iron-dependent repressor homolog; Idr2.
      
 0.616
pgi
Peroxidase / catalase; Pgi.
     
 0.612
