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

ygaAPutative EBP family regulator; Required for the expression of anaerobic nitric oxide (NO) reductase, acts as a transcriptional activator for at least the norVW operon. Activation also requires sigma-54. (506 aa)    
Predicted Functional Partners:
norV
Putative flavoprotein; Anaerobic nitric oxide reductase; uses NADH to detoxify nitric oxide (NO), protecting several 4Fe-4S NO-sensitive enzymes. Has at least 2 reductase partners, only one of which (NorW, flavorubredoxin reductase) has been identified. NO probably binds to the di-iron center; electrons enter from the NorW at rubredoxin and are transferred sequentially to the FMN center and the di-iron center. Also able to function as an aerobic oxygen reductase; In the N-terminal section; belongs to the zinc metallo- hydrolase group 3 family.
  
  
 0.964
hmpA
Dihydropteridine reductase 2; Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and NAD(P)H to convert NO to nitrate, which protects the bacterium from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress. Belongs to the globin family. Two-domain flavohemoproteins subfamily.
     
 0.942
yjeB
Putative negative regulator; Nitric oxide-sensitive repressor of genes involved in protecting the cell against nitrosative stress. May require iron for activity. Represses hmp expression under conditions of elevated intracellular iron concentrations, in the absence of nitric oxide.
      
 0.935
ygbD
Putative oxidoreductase; One of at least two accessory proteins for anaerobic nitric oxide (NO) reductase. Reduces the rubredoxin moiety of NO reductase.
 
  
 0.926
rpoN
Sigma N factor of RNA polymerase; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of enzymes involved in arginine catabolism. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for the receipt of the melting signal from the remotely bound activator protein GlnG(NtrC).
 
   
 0.819
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).
      
 0.767
yfhP
Hypothetical protein; Regulates the transcription of several operons and genes involved in the biogenesis of Fe-S clusters and Fe-S-containing proteins.
      
 0.752
nrfA
Nitrite reductase periplasmic cytochrome c(552); Catalyzes the reduction of nitrite to ammonia, consuming six electrons in the process; Belongs to the cytochrome c-552 family.
      
 0.697
glnG
EBP family response regulator in two-component regulatory system with GlnL; Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
  
 
 
0.633
oxyR
Regulatory protein sensor for oxidative stress; Regulates intracellular hydrogen peroxide (LysR family); similar to E. coli activator, hydrogen peroxide-inducible genes (AAC76943.1); Blastp hit to AAC76943.1 (305 aa), 95% identity in aa 1 - 305; Belongs to the LysR transcriptional regulatory family.
