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

Score
trxBThioredoxin reductase, FAD/NAD(P)-binding; Thioredoxin reductase; Belongs to the class-II pyridine nucleotide-disulfide oxidoreductase family. (321 aa)    
Predicted Functional Partners:
trxA
Thioredoxin 1; Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions.
 
 0.999
trxC
Thioredoxin 2; Efficient electron donor for the essential enzyme ribonucleotide reductase. Is also able to reduce the interchain disulfide bridges of insulin.
  
 0.993
ahpC
Alkyl hydroperoxide reductase, C22 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. Is the primary scavenger for endogenously generated hydrogen peroxides; Belongs to the peroxiredoxin family. AhpC/Prx1 subfamily.
  
 
 0.990
selD
Selenophosphate synthase; Synthesizes selenophosphate from selenide and ATP; Belongs to the selenophosphate synthase 1 family. Class I subfamily.
   
 
 0.948
sufS
Cysteine desulfurase, stimulated by SufE; Cysteine desulfurases mobilize the sulfur from L-cysteine to yield L-alanine, an essential step in sulfur metabolism for biosynthesis of a variety of sulfur-containing biomolecules. Component of the suf operon, which is activated and required under specific conditions such as oxidative stress and iron limitation. Acts as a potent selenocysteine lyase in vitro, that mobilizes selenium from L- selenocysteine. Selenocysteine lyase activity is however unsure in vivo. Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. Csd [...]

ygfK
Putative Fe-S subunit oxidoreductase subunit; Could be an iron-sulfur flavoprotein with NADPH:O(2) oxidoreductase activity.
  
 
 0.940
dsbC
Protein disulfide isomerase II; Acts as a disulfide isomerase, interacting with incorrectly folded proteins to correct non-native disulfide bonds. DsbG and DsbC are part of a periplasmic reducing system that controls the level of cysteine sulfenylation, and provides reducing equivalents to rescue oxidatively damaged secreted proteins. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbC is reoxidized by DsbD.
  
  
 0.922
grxA
Glutaredoxin 1, redox coenzyme for ribonucleotide reductase (RNR1a); The disulfide bond functions as an electron carrier in the glutathione-dependent synthesis of deoxyribonucleotides by the enzyme ribonucleotide reductase. In addition, it is also involved in reducing some disulfide bonds in a coupled system with glutathione reductase; Belongs to the glutaredoxin family.
   
 
 0.914
ynfE
Putative selenate reductase, periplasmic; Terminal reductase during anaerobic growth on various sulfoxide and N-oxide compounds; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
     
 0.901
ynfF
S- and N-oxide reductase, A subunit, periplasmic; Terminal reductase during anaerobic growth on various sulfoxide and N-oxide compounds.
     
 0.901
