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

mrgAMetalloregulation DNA-binding stress protein; Forms highly stable, multimeric protein-DNA complexes which accumulate in stationary-phase cells and protect against oxidative killing; Belongs to the Dps family. (153 aa)    
Predicted Functional Partners:
perR
Transcriptional regulator (Fur family); Hydrogen and organic peroxide sensor. Represses the expression of a regulon of peroxide-inducible genes such as katA, ahpC, ahpF, the heme biosynthesis operon (hemAXCDBL), fur, perR, zosA and mrgA; Belongs to the Fur family.
  
  
 0.935
katA
Vegetative catalase 1; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide.
  
  
 0.896
zosA
Zn transporter; Couples the hydrolysis of ATP with the transport of zinc into the cell. Plays an important role in protecting cells against oxidative stress. ZosA-mediated zinc transport is required for post- transcriptional control of comK and competence development.
  
  
 0.895
ahpC
Alkyl hydroperoxide reductase (small subunit); 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.
  
  
 0.818
ahpF
Alkyl hydroperoxide reductase (large subunit); Transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (By similarity).
  
  
 0.759
sodA
Superoxide dismutase; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems; Belongs to the iron/manganese superoxide dismutase family.
  
  
 0.723
ohrR
Transcriptional regulator sensing organic peroxides; Organic peroxide sensor. Represses the expression of the peroxide-inducible gene ohrA by cooperative binding to two inverted repeat elements.
   
  
 0.682
fbpA
Regulator of iron homeostasis; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type r: regulator.
      
 0.681
katX
Major catalase in spores; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide; Belongs to the catalase family.
  
  
 0.653
trxA
Thioredoxin; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions.
   
  
 0.609
