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 (nadA); Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate. (307 aa)    
Predicted Functional Partners:
nadC
Nicotinate-nucleotide pyrophosphorylase (nadC); Involved in the catabolism of quinolinic acid (QA). Belongs to the NadC/ModD family.
 
 0.999
nadX
Conserved hypothetical protein; Specifically catalyzes the NAD or NADP-dependent dehydrogenation of L-aspartate to iminoaspartate.
    
 0.950
nadE
NH(3)-dependent NAD+ synthetase (nadE); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
  
  
 0.942
mptD
Conserved hypothetical protein; Catalyzes the conversion of 7,8-dihydroneopterin (H2Neo) to 6-hydroxymethyl-7,8-dihydropterin (6-HMD).
       0.902
MJ_0409
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0409.
       0.839
MJ_0033
Succinate dehydrogenase, flavoprotein subunit (sdhA); Similar to GP:1524302 percent identity: 41.63; identified by sequence similarity; putative.
   
 0.818
MJ_0410
Hypothetical protein; Similar to PID:1174351 percent identity: 32.34; identified by sequence similarity; putative.
       0.806
hisF
Imidazoleglycerol-phosphate synthase, cyclase subunit (hisF); IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit (By similarity).
       0.783
MJ_1434
Endonuclease III, putative (nth2); Similar to GB:U11289 SP:P39788 PID:533099 PID:1146249 GB:AL009126 percent identity: 26.82; identified by sequence similarity; putative.
      0.747
MJ_0406
Ribokinase (rbsK); Catalyzes the phosphorylation of a wide range of nucleosides to yield nucleoside monophosphates. Shows the highest activity for inosine, guanosine and cytidine, but very poor kinase activity with adenosine, thymidine, uridine and xanthosine. ATP is the best phosphate donor, but can also use ITP and GTP. Shows extremely low activity with fructose-6-phosphate; Belongs to the carbohydrate kinase PfkB family.
