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

fldBFlavodoxin 2; Low-potential electron donor to a number of redox enzymes. Belongs to the flavodoxin family. (173 aa)    
Predicted Functional Partners:
xerD
Site-specific recombinase; Site-specific tyrosine recombinase, which acts by catalyzing the cutting and rejoining of the recombining DNA molecules. Binds cooperatively to specific DNA consensus sequences that are separated from XerC binding sites by a short central region, forming the heterotetrameric XerC-XerD complex that recombines DNA substrates. The complex is essential to convert dimers of the bacterial chromosome into monomers to permit their segregation at cell division. It also contributes to the segregational stability of plasmids. In the complex XerD specifically exchanges t [...]

dsbC
Protein disulfide isomerase II; Required for disulfide bond formation in some periplasmic proteins. Acts by transferring its disulfide bond to other proteins and is reduced in the process. DsbC is reoxidized by a yet uncharacterized protein. Also acts as a disulfide isomerase.
     
 0.664
recJ
ssDNA exonuclease; Single-stranded-DNA-specific exonuclease. Required for many types of recombinational events, although the stringency of the requirement for RecJ appears to vary with the type of recombinational event monitored and the other recombination gene products which are available.
  
  
 0.657
entB
Similar to E. coli 2,3-dihydro-2,3-dihydroxybenzoate synthetase, isochroismatase (AAC73696.1); Blastp hit to AAC73696.1 (285 aa), 88% identity in aa 1 - 285.
   
    0.624
nifJ
Similar to E. coli putative oxidoreductase, Fe-S subunit (AAC74460.1); Blastp hit to AAC74460.1 (1174 aa), 92% identity in aa 1 - 1174.
 
   
 0.610
nfo
Endonuclease IV; Endonuclease IV plays a role in DNA repair. It cleaves phosphodiester bonds at apurinic or apyrimidinic (AP) sites, generating a 3'-hydroxyl group and a 5'-terminal sugar phosphate.
   
  
 0.529
grxA
Redox coenzyme for glutathione-dependent ribonucleotide reductase glutaredoxin1; 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 disulfides in a coupled system with glutathione reductase (By similarity); Belongs to the glutaredoxin family.
      
 0.523
lysS
Similar to E. coli lysine tRNA synthetase, constitutive; suppressor of ColE1 mutation in primer RNA (AAC75928.1); Blastp hit to AAC75928.1 (505 aa), 95% identity in aa 1 - 505; Belongs to the class-II aminoacyl-tRNA synthetase family.
     
 0.461
soxR
Redox-sensing transcriptional activator SoxR; Activates the transcription of the soxS gene which itself controls the superoxide response regulon. SoxR contains a 2Fe-2S iron- sulfur cluster that may act as a redox sensor system that recognizes superoxide. The variable redox state of the Fe-S cluster is employed in vivo to modulate the transcriptional activity of SoxR in response to specific types of oxidative stress (By similarity).
     
 0.456
ahpF
Alkyl hydroperoxide reductase, F52a subunit; Serves to protect the cell against DNA damage by alkyl hydroperoxides. It can use either NADH or NADPH as electron donor for direct reduction of redox dyes or of alkyl hydroperoxides when combined with the AhpC protein; Belongs to the class-II pyridine nucleotide-disulfide oxidoreductase family.
