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; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (340 aa)    
Predicted Functional Partners:
amb3884
Aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
 0.999
amb3885
Nicotinate-nucleotide pyrophosphorylase; Belongs to the NadC/ModD family.
 
 0.999
amb2953
Nicotinate-nucleotide pyrophosphorylase; Belongs to the NadC/ModD family.
 
  
 0.964
amb3883
CRP/FNR family transcriptional regulator, cyclic AMP receptor protein; cAMP-binding protein - catabolite gene activator and regulatory subunit of cAMP-dependent protein kinase.
       0.737
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
  
 0.733
amb3882
Hypothetical protein.
       0.732
amb1852
Serine acetyltransferase.
  
    0.690
amb3031
Serine acetyltransferase.
  
    0.690
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.
      0.633
amb2341
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.
