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.

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.
 
 
0.924
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
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.
  
  
 0.886
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.
  
  
 0.874
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).
  
  
 0.843
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.
  
 
 0.774
ydeM
Putative dehydratase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
   
 0.669
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.
  
 
 0.600
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.
   
  
 0.557
tpx
Putative 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.
   
  
 0.523
