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

Score
norVPutative 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. (479 aa)    
Predicted Functional Partners:
ygbD
Putative oxidoreductase; One of at least two accessory proteins for anaerobic nitric oxide (NO) reductase. Reduces the rubredoxin moiety of NO reductase.
  
 0.998
nirB
Similar to E. coli nitrite reductase (NAD(P)H) subunit (AAC76390.1); Blastp hit to AAC76390.1 (847 aa), 95% identity in aa 1 - 847; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
 
 0.979
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.
  
  
 0.974
ygaA
Putative 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.
  
  
 0.964
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.
      
 0.950
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.
     
 0.912
hcp
Hybrid cluster protein; Catalyzes the reduction of hydroxylamine to form NH(3) and H(2)O.
 
   
 0.903
ytfE
Putative cell morphogenesis; Di-iron-containing protein involved in the repair of iron- sulfur clusters damaged by oxidative and nitrosative stress conditions.
  
  
 0.824
narG
Similar to E. coli nitrate reductase 1, alpha subunit (AAC74308.1); Blastp hit to AAC74308.1 (1247 aa), 95% identity in aa 1 - 1247; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
      
 0.761
yggW
Putative oxidase; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently. Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine. Belongs to the anaerobic coproporphyrinogen-III oxidase family.
