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

fdnGNitrate-inducible formate dehydrogenase molybdopterin-binding subunit FdnG; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family. (1004 aa)    
Predicted Functional Partners:
fdnH
Nitrate-inducible formate dehydrogenase iron-sulfur subunit FdnH; The beta chain is an electron transfer unit containing 4 cysteine clusters involved in the formation of iron-sulfur centers.
 
 0.991
fdnI
Nitrate-inducible formate dehydrogenase cytochrome b subunit FdnI.
 
 
 0.991
fdhE
Nitrate-inducible formate dehydrogenase chaperone FdhE; Necessary for formate dehydrogenase activity. Belongs to the FdhE family.
 
 0.980
napB
Periplasmic nitrate reductase cytochrome c subunit NapB; Electron transfer subunit of the periplasmic nitrate reductase complex NapAB. Receives electrons from the membrane-anchored tetraheme c-type CymA protein and transfers these to NapA subunit, thus allowing electron flow between membrane and periplasm. Not essential for nitrate reduction but confers advantage to the organism when grown on nitrate and thereby a fitness gain in utilizing nitrate. Belongs to the NapB family.
  
 0.943
selA
L-seryl-tRNA selenium transferase SelA; Converts seryl-tRNA(Sec) to selenocysteinyl-tRNA(Sec) required for selenoprotein biosynthesis.
 
  
 0.928
selB
Selenocysteine-specific translation elongation factor SelB.
 
  
 0.916
purU
Formyltetrahydrofolate deformylase PurU; Catalyzes the hydrolysis of 10-formyltetrahydrofolate (formyl-FH4) to formate and tetrahydrofolate (FH4).
    
  0.902
frmB
S-formylglutathione hydrolase FrmB; Serine hydrolase involved in the detoxification of formaldehyde.
     
  0.900
napD
Periplasmic nitrate reductase chaperone NapD; Chaperone for NapA, the catalytic subunit of the periplasmic nitrate reductase. It binds directly and specifically to the twin- arginine signal peptide of NapA, preventing premature interaction with the Tat translocase and premature export.
  
 
 0.894
napG
Periplasmic nitrate reductase ferredoxin component NapG.
  
 0.863
