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

nadEGlutamine-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source. (556 aa)    
Predicted Functional Partners:
nadD
Putative nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
  
 
 0.958
nadK
Putative inorganic polyphosphate/ATP-NAD kinase (Poly(P)/ATP NAD kinase); Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP.
    
 0.955
pntB
Pyridine nucleotide transhydrogenase (proton pump), beta subunit; The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane; Belongs to the PNT beta subunit family.
     
 0.935
pntA
Nicotinamide nucleotide transhydrogenase, subunit alpha1; Function of homologous gene experimentally demonstrated in an other organism; enzyme.
     
 0.909
pntAB
NAD(P) transhydrogenase subunit alpha part 2; Function of strongly homologous gene; enzyme.
     
 0.909
CCQ75406.1
Putative NUDIX hydrolase; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
  
 
 0.909
CCQ73791.1
Protein mazG, nucleoside triphosphate pyrophosphohydrolase; Function of strongly homologous gene; enzyme.
    
  0.900
cysS
Cysteine tRNA synthetase; Function of homologous gene experimentally demonstrated in an other organism; enzyme; Belongs to the class-I aminoacyl-tRNA synthetase family.
     
 0.849
CCQ75253.1
Protein of unknown function; No homology to any previously reported sequences.
       0.773
rarA
Putative polynucleotide enzyme with nucleotide triphosphate hydrolase domain; Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.
