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:
some 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

dsbGThiol:disulfide interchange protein, periplasmic; Involved in disulfide bond formation. 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 such as ErfK, YbiS and YnhG. Probably also functions as a disulfide isomerase with a narrower substrate specificity than DsbC. DsbG is maintained in a reduced state by DsbD. Displays chaperone activity in both redox states in vitro (248 aa)    
Predicted Functional Partners:
dsbD
Thiol:disulfide interchange protein and activator of dsbc; Required to facilitate the formation of correct disulfide bonds in some periplasmic proteins and for the assembly of the periplasmic c-type cytochromes. Acts by transferring electrons from cytoplasmic thioredoxin to the periplasm, thereby maintaining the active site of DsbC, DsbE and DsbG in a reduced state. This transfer involves a cascade of disulfide bond formation and reduction steps
  
  
 0.971
dsbB
Oxidoreductase that catalyzes reoxidation of dsba protein disulfide isomerase i; Required for disulfide bond formation in some periplasmic proteins such as PhoA or OmpA. Acts by oxidizing the DsbA protein. PhoP-regulated transcription is redox-sensitive, being activated when the periplasm becomes more reducing (deletion of dsbA/dsbB, treatment with dithiothreitol). MgrB acts between DsbA/DsbB and PhoP/PhoQ in this pathway
  
  
 0.926
dsbE
Cytochrome c biogenesis protein ccmg, thiol:disulfide interchange protein dsbe; Involved in disulfide bond formation. Catalyzes a late, reductive step in the assembly of periplasmic c-type cytochromes, probably the reduction of disulfide bonds of the apocytochrome c to allow covalent linkage with the heme. Possible subunit of a heme lyase. DsbE is maintained in a reduced state by DsbD
  
  
 0.926
dsbA
Protein dithiol oxidoreductase (disulfide-forming); Required for disulfide bond formation in some periplasmic proteins such as PhoA or OmpA. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbA is reoxidized by DsbB. Required for pilus biogenesis. PhoP-regulated transcription is redox-sensitive, being activated when the periplasm becomes more reducing (deletion of dsbA/dsbB, treatment with dithiothreitol). MgrB acts between DsbA/DsbB and PhoP/PhoQ in this pathway
      
 0.921
ldtB
L,d-transpeptidase linking lpp to murein; Responsible, at least in part, for anchoring of the major outer membrane lipoprotein (Lpp, also known as the Braun lipoprotein) to the peptidoglycan via a meso-diaminopimelyl-L-Lys- bond on the terminal residue of Lpp. Can be oxidized in vivo, its reduction depends preferentially on DsbG, although DsbC is able to partially replace DsbG
      
 0.698
trxC
Reduced thioredoxin 2; Efficient electron donor for the essential enzyme ribonucleotide reductase. Is also able to reduce the interchain disulfide bridges of insulin
      
 0.625
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
      
 0.550
fhuF
Ferric iron reductase involved in ferric hydroximate transport; Involved in the reduction of ferric iron in cytoplasmic ferrioxamine B
  
   
 0.515
ybdO
Putative lysr family dna-binding transcriptional regulator ybdo; Belongs to the LysR transcriptional regulatory family
   
   0.492
trxB
Thioredoxin reductase, fad/nad(p)-binding; Belongs to the class-II pyridine nucleotide-disulfide oxidoreductase family
      
 0.489
