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

asr1309NifU like protein; ORF_ID:asr1309. (76 aa)    
Predicted Functional Partners:
all0945
Succinate dehydrogenase iron-sulfur protein subunit; ORF_ID:all0945; Belongs to the succinate dehydrogenase/fumarate reductase iron-sulfur protein family.
  
 
 0.694
nifU
Nitrogen fixation protein; May be involved in the formation or repair of [Fe-S] clusters present in iron-sulfur proteins.
 
 
0.651
alr2771
Dihydroxyacid dehydratase; ORF_ID:alr2771; Belongs to the IlvD/Edd family.
  
 
 0.569
nifS
Nitrogenase cofactor synthesis protein; Catalyzes the removal of elemental sulfur atoms from cysteine to produce alanine. Seems to participate in the biosynthesis of the nitrogenase metalloclusters by providing the inorganic sulfur required for the Fe-S core formation; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. NifS/IscS subfamily.
 
 
 0.541
alr1310
ORF_ID:alr1310; hypothetical protein.
       0.522
alr2505
Cysteine desulfurase IscS; ORF_ID:alr2505; putative aminotransferase; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family.
  
 
 0.472
nifS-2
class-V aminotransferase; ORF_ID:alr3088; nifS gene product.
  
 
 0.472
nifJ
Pyruvate flavodoxin dehydrogenase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin.
     
 0.452
nifJ-2
Pyruvate-flavodoxin dehydrogenase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin, which reduces nitrogenase.
     
 0.452
hesB
HesB protein; May be required for efficient nitrogen fixation.
  
 
 0.431
