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

ygbAUncharacterized protein. (117 aa)    
Predicted Functional Partners:
ytfE
Iron-sulfur cluster repair protein RIC; Di-iron-containing protein involved in the repair of iron- sulfur clusters damaged by oxidative and nitrosative stress conditions.
  
  
 0.909
yoaG
Uncharacterized protein.
   
  
 0.825
hcr
HCP oxidoreductase, NADH-dependent; NADH oxidoreductase acting in concert with HCP.
   
  
 0.823
tehA
Potassium-tellurite ethidium and proflavin transporter; Responsible for potassium tellurite resistance when present in high copy number. Ion channel involved in potassium tellurite resistance (By similarity). Otherwise, phenotypically silent. Belongs to the tellurite-resistance/dicarboxylate transporter (TDT) family.
  
   
 0.819
hmp
Fused nitric oxide dioxygenase/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. Various electron acceptors are also reduced by HMP in vitro, including dihydropterine, ferrisiderophores, ferric citrate, cytochrome c, nitrite, S-nitrosoglutathione, and alkylhydroperoxides. However, it is unknown if th [...]
   
  
 0.819
nsrR
Nitric oxide-sensitive repressor for NO regulon; Nitric oxide-sensitive repressor of genes involved in protecting the cell against nitrosative stress, such as ytfE, hmpA and ygbA. May require iron for activity. Does not regulates its own transcription.
      
 0.790
yfhH
Putative DNA-binding transcriptional regulator.
   
  
 0.733
pphB
Serine/threonine-specific protein phosphatase 2; Has been shown, in vitro, to act on Ser, Thr and Tyr- phosphorylated substrates; Belongs to the PPP phosphatase family.
     
 0.714
hcp
Hybrid-cluster [4Fe-2S-2O] subunit of anaerobic terminal reductases; Catalyzes the reduction of hydroxylamine to form NH(3) and H(2)O. Is also able to reduce hydroxylamine analogs such as methylhydroxylamine and hydroxyquinone. Might have a role as a scavenger of potentially toxic by-products of nitrate metabolism. Belongs to the HCP family.
  
  
 0.650
yeaR
DUF1971 family protein, nitrate-inducible; Protein involved in xenobiotic metabolic process.
   
  
 0.589
