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 complex, subunit A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate; Belongs to the quinolinate synthase A family. Type 1 subfamily. (349 aa)    
Predicted Functional Partners:
nadB
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
 0.999
nadC
(nicotinate-nucleotide pyrophosphorylase) identified by sequencesimilarity; putative InterPro: Nicotinate-nucleotide pyrophosphorylase; High confidence in function and specificity; Belongs to the NadC/ModD family.
 
 0.998
cysE
Serine acetyltransferase; Identified by sequence similarity; putative InterPro: Bacterial transferase hexapeptide repeat; High confidence in function and specificity.
  
    0.715
dapA
Dihydrodipicolinate synthase; Catalyzes the condensation of (S)-aspartate-beta-semialdehyde [(S)-ASA] and pyruvate to 4-hydroxy-tetrahydrodipicolinate (HTPA).
 
  
 0.669
gmk-2
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
    0.631
ribD
(S)-2-hydroxy-fatty-acid dehydrogenase; 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.
  
  
 0.540
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 1 subfamily.
      0.534
birA
biotin-[acetyl-CoA-carboxylase] ligase; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5'-adenylate (BirA-bio-5'-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon.
     
 0.521
nadE
NAD+ synthase (glutamine-hydrolysing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.489
purL
Phosphoribosylformylglycinamidine synthase; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate.
