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 synthase A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (302 aa)    
Predicted Functional Partners:
nadB_1
L-aspartate oxidase.
 0.999
nadC
Probable nicotinate-nucleotide pyrophosphorylase [carboxylating]; Belongs to the NadC/ModD family.
 
 0.999
cysE
Serine acetyltransferase.
  
    0.794
valS
Valine--tRNA ligase; 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 1 subfamily.
      0.688
ribD_2
Riboflavin biosynthesis protein RibD; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.
  
  
 0.679
niaR
Probable transcription repressor NiaR.
  
  
 0.651
birA
Bifunctional protein BirA; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
     
 0.642
purL
Phosphoribosylformylglycinamidine synthase.
  
  
 0.627
nadE
Glutamine-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.627
dapA
Dihydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
 
  
 0.573
