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

fhlAFormate hydrogen-lyase transcriptional activator for fdhF, hyc and hyp operons; Required for induction of expression of the formate dehydrogenase H and hydrogenase-3 structural genes. (692 aa)    
Predicted Functional Partners:
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).
 
   
 0.831
hfq
Host factor I for bacteriophage Q beta replication; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs (By similarity). Plays a central regulatory role in the microbial response to space flight conditions. Is essential for virulence and is required for efficient invasion of non-phagocytic cells.
   
  
 0.782
rpoS
Sigma S (sigma 38) 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 the master transcriptional regulator of the stationary phase and the general stress response.
      
 0.773
hypE
Putative hydrogenase expression/formation protein; Similar to E. coli plays structural role in maturation of all 3 hydrogenases (AAC75772.1); Blastp hit to AAC75772.1 (322 aa), 91% identity in aa 1 - 322.
  
  
 0.747
galK
Galactokinase; Catalyzes the transfer of the gamma-phosphate of ATP to D- galactose to form alpha-D-galactose-1-phosphate (Gal-1-P). Belongs to the GHMP kinase family. GalK subfamily.
      
 0.658
hypD
Putative hydrogenase expression/formation protein; Similar to E. coli pleiotrophic effects on 3 hydrogenase isozymes (AAC75771.1); Blastp hit to AAC75771.1 (373 aa), 94% identity in aa 1 - 372; Belongs to the HypD family.
  
    0.574
hycI
Similar to E. coli protease involved in processing C-terminal end of the large subunit of hydrogenase 3 (AAC75759.1); Blastp hit to AAC75759.1 (156 aa), 91% identity in aa 1 - 155.
 
  
 0.563
sodB
Iron superoxide dismutase; Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems; Belongs to the iron/manganese superoxide dismutase family.
     
 0.548
arcB
Sensory histidine kinase in two-component regulatory system with ArcA; Senses redox conditions; similar to E. coli aerobic respiration sensor-response protein; histidine protein kinase/phosphatase, sensor for arcA (AAC76242.1); Blastp hit to AAC76242.1 (776 aa), 93% identity in aa 1 - 776.
   
 
 0.545
hypB
Hydrogenase-3 accessory protein; Assembly of metallocenter; similar to E. coli guanine-nucleotide binding protein, functions as nickel donor for large subunit of hydrogenase 3 (AAC75769.1); Blastp hit to AAC75769.1 (290 aa), 94% identity in aa 1 - 290.
