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

yqjFPutative quinol oxidase subunit. (130 aa)    
Predicted Functional Partners:
yhaJ
LysR family putative transcriptional regulator; Positive regulator, may be partially responsible for expression of neighboring gene dlsT (yhaO) (By similarity).
      
 0.902
yhaK
Redox-sensitive bicupin; Does not have quercetin 2,3-dioxygenase activity. Belongs to the pirin family.
  
  
 0.831
ybiJ
DUF1471 family putative periplasmic protein.
   
  
 0.808
yhhW
Quercetinase activity in vitro; Has quercetin 2,3-dioxygenase activity in vitro. Its physiological role is unknown; however, may provide a mechanism that would avoid inhibition of key cellular proteins, such as DNA gyrase, by quercetin.
  
  
 0.789
ygdD
UPF0382 family inner membrane protein.
      
 0.737
azoR
NADH-azoreductase, FMN-dependent; Catalyzes the reductive cleavage of azo bond in aromatic azo compounds to the corresponding amines. Requires NADH, but not NADPH, as an electron donor for its activity. The enzyme can reduce ethyl red and methyl red, but is not able to convert sulfonated azo dyes; Belongs to the azoreductase type 1 family.
 
  
 0.690
yqjG
Putative S-transferase; Catalyzes glutathione (GSH)-dependent reduction of glutathionyl-hydroquinones (GS-HQs) to the corresponding hydroquinones. Can use a variety of GS-HQs as substrates, such as GS-p-hydroquinone (GS-HQ), GS-hydroxy-p-hydroquinone (GS-HHQ), GS-methyl-p-hydroquinone (GS-MHQ), GS-menadiol, and GS-trichloro-p-hydroquinone (GS-TriCH). Also displays GSH-dependent disulfide-bond reduction activity toward HED (2- hydroxyethyl disulfide), and is able to catalyze DMA (dimethylarsinate) reduction. Exhibits no GSH transferase activity with 1-chloro-2,4- dinitrobenzene (CDNB).
  
    0.609
ygiD
4,5- DOPA-extradiol-dioxygenase; In vitro, opens the cyclic ring of dihydroxy-phenylalanine (DOPA) between carbons 4 and 5, thus producing an unstable seco-DOPA that rearranges nonenzymatically to betalamic acid. The physiological substrate is unknown.
  
  
 0.595
yjfZ
Uncharacterized protein.
      
 0.525
yghQ
Putative inner membrane polysaccharide flippase.
      
 0.505
