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. (301 aa)    
Predicted Functional Partners:
nadB
L-aspartate oxidase; Identified by match to protein family HMM PF00890; match to protein family HMM PF07992.
 
 0.999
nadC
Nicotinate-nucleotide diphosphorylase (carboxylating); Identified by 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
cysE
Serine O-acetyltransferase; Identified by similarity to SP:Q06750; match to protein family HMM PF00132; match to protein family HMM TIGR01172.
  
    0.744
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.
      0.697
CPF_0387
Putative nicotinamide mononucleotide transporter PnuC; Identified by similarity to SP:P31215; match to protein family HMM PF04973; match to protein family HMM TIGR01528.
  
  
 0.690
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.
  
  
 0.657
nadE
Glutamine-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
  
  
 0.641
folBK
Dihydroneopterin aldolase/2-amino-4-hydroxy-6-hydroxymethyldihydropteridine pyrophosphokinase; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin.
     
 0.639
birA
BirA bifunctional protein; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a repressor; Belongs to the biotin--protein ligase family.
     
 0.616
CPF_0671
Phosphoribosylformylglycinamidine synthase; Identified by match to protein family HMM PF02769; match to protein family HMM TIGR01857.
  
  
 0.607
