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

trxA_3Thioredoxin serves as a general protein disulphide oxidoreductase. It interacts with a broad range of proteins by a redox mechanism based on reversible oxidation of two cysteine thiol groups to a disulphide, accompanied by the transfer of two electrons and two protons. The net result is the covalent interconversion of a disulphide and a dithiol. In the NADPH-dependent protein disulphide reduction, thioredoxin reductase (TR) catalyses the reduction of oxidised thioredoxin (trx) by NADPH using FAD and its redox-active disulphide; reduced thioredoxin then directly reduces the disulphide i [...] (150 aa)    
Predicted Functional Partners:
PSM36_0201
SpoU; tRNA G18 (ribose-2'-O)-methylase SpoU [Translation, ribosomal structure and biogenesis]; High confidence in function and specificity.
       0.633
trxB1
This model describes thioredoxin-disulfide reductase, a member of the pyridine nucleotide-disulphide oxidoreductases (pfam00070). [Energy metabolism, Electron transport]; High confidence in function and specificity.
 
 
 0.629
groL
GroEL_like type I chaperonin; Prevents misfolding and promotes the refolding and proper assembly of unfolded polypeptides generated under stress conditions.
 
 
 0.617
trxB3
Thioredoxin + NADP+ = thioredoxin disulfide + NADPH; High confidence in function and specificity.
 
 
 0.606
PSM36_2445
This model describes dihydrolipoamide dehydrogenase, a flavoprotein that acts in a number of ways. It is the E3 component of dehydrogenase complexes for pyruvate, 2-oxoglutarate, 2-oxoisovalerate, and acetoin. It can also serve as the L protein of the glycine cleavage system. This family includes a few members known to have distinct functions (ferric leghemoglobin reductase and NADH:ferredoxin oxidoreductase) but that may be predicted by homology to act as dihydrolipoamide dehydrogenase as well. The motif GGXCXXXGCXP near the N-terminus contains a redox-active disulfide; High confidenc [...]

ahpC
Alkyl hydroperoxide reductase subunit 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.
  
 
 0.526
PSM36_1521
Glyceraldehyde-3-phosphate dehydrogenase, cytosolic; D-glyceraldehyde 3-phosphate + phosphate + NAD+ = 3-phospho-D-glyceroyl phosphate + NADH; High confidence in function and specificity; Belongs to the glyceraldehyde-3-phosphate dehydrogenase family.
  
 
 0.520
gltB
2 L-glutamate + NADP(+) <=> L-glutamine + 2-oxoglutarate + NADPH; High confidence in function and specificity.
