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

trxA2Thioredoxin. (128 aa)    
Predicted Functional Partners:
ahpC
Alkyl hydroperoxide reductase C; 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.
  
 0.984
msrA
Peptide-methionine (S)-S-oxide 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.
   
 0.979
CBL55565.1
Hypothetical protein; Signal peptid detected according to SignalP. 3 TM domains according to TMHMM.
 
     0.936
msrB
L-methionine (S)-S-oxide reductase; L-methionine + thioredoxin disulfide + H(2)O <=> L-methionine (S)-S-oxide + thioredoxin # The reaction occurs in the opposite direction to that given above. Dithiothreitol can replace reduced thioredoxin. Methionine sulfoxide reduction is an important process, by which cells regulate biological processes and cope with oxidative stress.
   
 0.869
nrdJ
Vitamin B12-dependent ribonucleotide reductase (Ribonucleoside-diphosphate reductase NrdJ); Catalyzes the reduction of ribonucleotides to deoxyribonucleotides. May function to provide a pool of deoxyribonucleotide precursors for DNA repair during oxygen limitation and/or for immediate growth after restoration of oxygen.
  
 
 0.866
sseB
Thiosulfate + Cyanide <=> Sulfite + Thiocyanate.
    
 0.840
trxB
Thioredoxin reductase.
  
 
 0.818
CBL56490.1
5.2 Protein of unknown function similar to proteins from other organisms; Belongs to the UPF0301 (AlgH) family.
   
 
 0.773
rpoB
DNA-directed RNA polymerase subunit beta; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
 0.757
merA
Pyridine nucleotide-disulphide oxidoreductase; Hg + NADP+ + H+ <=> Hg2+ + NADPH.
   
 0.727
