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

nifQ-3NifQ protein,Protein involved in biosynthesis of iron-molybdenum cofactor of nitrogenase; Function of strongly homologous gene; factor. (187 aa)    
Predicted Functional Partners:
nifX-2
NifX FeMo cofactor biosynthesis protein; Function of strongly homologous gene; cell process.
 
  
 0.924
XM1_3933
Ferredoxin; Function of homologous gene experimentally demonstrated in an other organism; carrier.
 
 0.919
nifS
Cysteine desulfurase; Function of strongly homologous gene; enzyme.
  
 0.898
iscS
Cysteine desulfurase (tRNA sulfurtransferase), PLP-dependent; Master enzyme that delivers sulfur to a number of partners involved in Fe-S cluster assembly, tRNA modification or cofactor biosynthesis. Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Functions as a sulfur delivery protein for Fe-S cluster synthesis onto IscU, an Fe-S scaffold assembly protein, as well as other S acceptor proteins; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
  
 0.898
hscB
Co-chaperone protein HscB homolog; Co-chaperone involved in the maturation of iron-sulfur cluster-containing proteins. Seems to help targeting proteins to be folded toward HscA; Belongs to the HscB family.
  
 
 0.873
nifW
Nitrogenase-stabilizing/protective protein NifW; Function of homologous gene experimentally demonstrated in an other organism; factor.
 
  
 0.870
nifZ
NifZ, nitrogenase P-cluster assembly; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
 
  
 0.865
nifB
FeMo cofactor biosynthesis protein NifB; Function of homologous gene experimentally demonstrated in an other organism; factor.
 
  
 0.864
nifX
Nitrogen fixation protein NifX; Function of homologous gene experimentally demonstrated in an other organism; factor.
 
  
 0.844
XM1_3944
Conserved protein of unknown function(containing probable nitrogen fixation protein domain,7-149); Homologs of previously reported genes of unknown function.
