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, A subunit; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (350 aa)    
Predicted Functional Partners:
SPO3244
L-aspartate oxidase, putative; Identified by similarity to GB:BAB54506.1; match to protein family HMM PF00890; match to protein family HMM PF02910.
 0.999
nadC
Nicotinate-nucleotide pyrophosphorylase; Identified by similarity to SP:P39666; match to protein family HMM PF01729; match to protein family HMM PF02749; match to protein family HMM TIGR00078; Belongs to the NadC/ModD family.
 
 0.999
nadX
Hypothetical protein; Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate.
    
 0.926
cysE
Serine O-acetyltransferase; Identified by similarity to SP:P05796; match to protein family HMM PF00132; match to protein family HMM PF06426; match to protein family HMM TIGR01172.
  
    0.821
pncB
Nicotinate phosphoribosyltransferase; Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP; Belongs to the NAPRTase family.
     
 0.728
ribD
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.
  
  
 0.702
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
  
 0.687
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.
      0.676
nadE
Glutamine-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.664
SPO2024
Aminotransferase; 'initially identified as a pseudogene, expression verified by proteomics'.
  
  
 0.537
