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 A; Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (304 aa)    
Predicted Functional Partners:
ABB49165.1
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
 
 0.999
ABB49252.1
Nicotinate-nucleotide pyrophosphorylase (carboxylating); Alternative locus ID: P9312_01981; Belongs to the NadC/ModD family.
 
 
 0.998
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.

ABB49740.1
Putative transcripton factor; Alternative locus ID: P9312_07101.
     
 0.632
ABB50419.1
Diaminohydroxyphosphoribosylaminopyrimidine deaminase; 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.

gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
    0.570
nadE
NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.561
ABB50357.1
Putative acetyltransferase; Alternative locus ID: P9312_14171.
  
    0.560
ABB50792.1
Serine O-acetyltransferase; Alternative locus ID: P9312_18821.
  
    0.560
ABB50855.1
Putative chloride channel; Alternative locus ID: P9312_19461.
