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

katAVegetative catalase 1; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. (483 aa)    
Predicted Functional Partners:
katE
Catalase 2; Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. Involved in sporulation.
 
0.941
glcD
Glycolate oxidase subunit; Component of a complex that catalyzes the oxidation of glycolate to glyoxylate. Is also able to oxidize D-lactate ((R)- lactate). Does not link directly to O(2), and 2,6-dichloroindophenol (DCIP) and phenazine methosulfate (PMS) can act as artificial electron acceptors in vitro, but the physiological molecule that functions as primary electron acceptor during glycolate oxidation is unknown. Belongs to the FAD-binding oxidoreductase/transferase type 4 family.
   
 0.913
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.
  
  
0.906
glcF
Glycolate oxidase iron-sulfur subunit; Component of a complex that catalyzes the oxidation of glycolate to glyoxylate. Is also able to oxidize D-lactate ((R)- lactate). Does not link directly to O(2), and 2,6-dichloroindophenol (DCIP) and phenazine methosulfate (PMS) can act as artificial electron acceptors in vitro, but the physiological molecule that functions as primary electron acceptor during glycolate oxidation is unknown.

mrgA
Metalloregulation 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.
  
  
 0.896
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.
  
 
 0.896
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.
  
  
 0.868
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).
  
  
 0.844
ydeM
Putative dehydratase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
   
 0.638
ykuU
Putative 2-cys peroxiredoxin; 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.
