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; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (341 aa)    
Predicted Functional Partners:
nadB
Aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.

KGI53338.1
Nicotinate-nucleotide pyrophosphorylase; Catalyzes the formation of pyridine-2,3-dicarboxylate and 5-phospho-alpha-D-ribose 1-diphosphate from nictinate D-ribonucleotide; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the NadC/ModD family.
 
 
 0.999
cysE
Serine acetyltransferase; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
    0.780
KGI53342.1
Phosphatidylserine decarboxylase; Catalyzes the formation of phosphatidylethanolamine (PtdEtn) from phosphatidylserine (PtdSer).
       0.779
KGI53341.1
Hypothetical protein; Involved in the import of queuosine (Q) precursors, required for Q precursor salvage; Belongs to the vitamin uptake transporter (VUT/ECF) (TC 2.A.88) family. Q precursor transporter subfamily.
       0.770
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
    0.715
KGI54408.1
Part of three member fumarate reductase enzyme complex FrdABC which catalyzes the reduction of fumarate to succinate during anaerobic respiration; FrdAB are the catalytic subcomplex consisting of a flavoprotein subunit and an iron-sulfur subunit, respectively; FrdC is the cytochrome b-556 subunit; the catalytic subunits are similar to succinate dehydrogenase SdhAB; Derived by automated computational analysis using gene prediction method: Protein Homology.
 
  
 0.629
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.
      0.622
ribD
Riboflavin biosynthesis protein RibD; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
  
 0.612
bioB
Biotin synthase; Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism; Belongs to the radical SAM superfamily. Biotin synthase family.
