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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

hmpFlavohemoprotein; 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; In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family (396 aa)    
Predicted Functional Partners:
ytfE
Iron-sulfur cluster repair protein YtfE; Di-iron-containing protein involved in the repair of iron-sulfur clusters damaged by oxidative and nitrosative stress conditions
  
  
 0.981
nsrR
HTH-type transcriptional repressor NsrR; 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
 
  
 0.929
yiiM
annotation not available
   
 0.905
norR
Anaerobic nitric oxide reductase transcription regulator NorR; 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. Not required for induction of the aerobic NO-detoxifying enzyme NO dioxygenase. Binds to the promoter region of norVW, to a consensus target sequence, GT-(N7)-AC, which is highly conserved among proteobacteria
     
 0.896
norW
Nitric oxide reductase FlRd-NAD(+) reductase; One of at least two accessory proteins for anaerobic nitric oxide (NO) reductase. Reduces the rubredoxin moiety of NO reductase; Belongs to the FAD-dependent oxidoreductase family
   
 
 0.896
nirB
Nitrite reductase (NAD(P)H) subunit; Protein involved in anaerobic respiration; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family
 
   
 0.882
hcp
Hydroxylamine reductase; 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
  
  
 0.846
norV
Anaerobic nitric oxide reductase flavorubredoxin; 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 reductase 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
  
  
 0.840
thiD
Hydroxymethylpyrimidine/phosphomethylpyrimidine kinase; Catalyzes the phosphorylation of hydroxymethylpyrimidine phosphate (HMP-P) to HMP-PP, and of HMP to HMP-P. Shows no activity with pyridoxal, pyridoxamine or pyridoxine; Belongs to the ThiD family
   
  
 0.821
thiM
Hydroxyethylthiazole kinase; Catalyzes the phosphorylation of the hydroxyl group of 4-methyl-5-beta-hydroxyethylthiazole (THZ); Belongs to the Thz kinase family
      
 0.811
