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

katACatalase (hktE); Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide; Belongs to the catalase family. (508 aa)    
Predicted Functional Partners:
sodA
Superoxide dismutase (sodA); 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.
  
 0.813
msrAB
Peptide methionine sulfoxide reductase (msrA); 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 (By similarity).
   
 
 0.804
PGdx
Membrane protein; 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; In the C-terminal section; belongs to the glutaredoxin family.
  
 
 0.775
HI_1163
Conserved hypothetical protein; Similar to GB:U00096 SP:P77748 PID:1742760 PID:1787977 percent identity: 60.82; identified by sequence similarity; putative.
   
 0.754
trxB
Thioredoxin reductase (trxB); Similar to GB:J03762 SP:P09625 PID:148073 PID:347239 GB:U00096 percent identity: 75.95; identified by sequence similarity; putative.
   
 
 0.726
hfq
Host factor-I protein (hfq); RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs. Belongs to the Hfq family.
    
 
 0.709
HI_0082
Predicted coding region HI0082; Hypothetical protein; identified by GeneMark; putative.
  
 0.690
bcp
Bacterioferritin comigratory protein (bcp); 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 and as sensor of hydrogen peroxide-mediated signaling events; Belongs to the peroxiredoxin family. BCP/PrxQ subfamily.
      
 0.646
potE
Putrescine-ornithine antiporter (potE); Catalyzes both the uptake and excretion of putrescine. The uptake of putrescine is dependent on the membrane potential and the excretion involves putrescine-ornithine antiporter activity. Belongs to the amino acid-polyamine-organocation (APC) superfamily. Basic amino acid/polyamine antiporter (APA) (TC 2.A.3.2) family.
     
 0.599
lldD
L-lactate dehydrogenase (lctD); Catalyzes the conversion of L-lactate to pyruvate. Is coupled to the respiratory chain; Belongs to the FMN-dependent alpha-hydroxy acid dehydrogenase family.
