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. (365 aa)    
Predicted Functional Partners:
nadC
[H] COG0157 Nicotinate-nucleotide pyrophosphorylase; Belongs to the NadC/ModD family.
 
 0.999
nadB
L-aspartate oxidase; Catalyzes the oxidation of L-aspartate to iminoaspartate.
 0.997
ispH
4-hydroxy-3-methylbut-2-enyl diphosphate reductase; Catalyzes the conversion of 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate (HMBPP) into a mixture of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Acts in the terminal step of the DOXP/MEP pathway for isoprenoid precursor biosynthesis. Belongs to the IspH family.
     
 0.836
ntpA
Nudix hydrolase; [LR] COG0494 NTP pyrophosphohydrolases including oxidative damage repair enzymes.
     
 0.788
KB13_357
Histidine triad protein; [FGR] COG0537 Diadenosine tetraphosphate (Ap4A) hydrolase and other HIT family hydrolases.
       0.782
cysE
Serine O-acetyltransferase; [R] COG0110 Acetyltransferase (isoleucine patch superfamily).
  
    0.695
lysA
Diaminopimelate decarboxylase; Specifically catalyzes the decarboxylation of meso- diaminopimelate (meso-DAP) to L-lysine.
     
 0.649
gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
    0.647
sdhA
[C] COG1053 Succinate dehydrogenase/fumarate reductase, flavoprotein subunit; Belongs to the FAD-dependent oxidoreductase 2 family. FRD/SDH subfamily.
   
 0.645
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.
