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

nadAQuinolinate synthetase A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (305 aa)    
Predicted Functional Partners:
nadC
Predicted nicotinate-nucleotide pyrophosphorylase; Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
 
 
 0.999
nadX
Predicted L-aspartate dehydrogenase; Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate.
    
 0.944
rnz
Predicted ribonuclease Z; Zinc phosphodiesterase, which displays some tRNA 3'- processing endonuclease activity. Probably involved in tRNA maturation, by removing a 3'-trailer from precursor tRNA; Belongs to the RNase Z family.
     
 0.631
tfrA
Thiol:fumarate reductase, subunit A; Catalyzes the reduction of fumarate with reduced coenzyme M (CoM-S-H) and coenzyme B (CoB-S-H). In vitro, is able to reduces fumarate with reduced benzyl viologen, oxidize CoM-S-H and CoB-S-H to CoM-S-S-CoB with methylene blue, and reduce CoM-S-S-CoB with reduced benzyl viologen. The enzyme has specificity for the two thiol compounds as the CoB--CoM heterodisulfide reductase. The enzyme is very sensitive to oxygen; Belongs to the FAD-dependent oxidoreductase 2 family.
 
   
 0.620
nadE
Predicted NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
  
  
 0.619
ADL58001.1
Predicted mechanosensitive ion channel.
       0.600
queE
Predicted glycyl radical-activating enzyme; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.
 
   
 0.574
valS
valyl-tRNA synthetase; Catalyzes the attachment of valine to tRNA(Val). As ValRS can inadvertently accommodate and process structurally similar amino acids such as threonine, to avoid such errors, it has a 'posttransfer' editing activity that hydrolyzes mischarged Thr-tRNA(Val) in a tRNA- dependent manner; Belongs to the class-I aminoacyl-tRNA synthetase family. ValS type 2 subfamily.
      0.526
hcgA
Hmd co-occurring protein HcgA.
  
  
 0.525
ADL59237.1
BioB-related protein.
  
  
 0.525
