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

nadKPutative inorganic polyphosphate/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. (294 aa)    
Predicted Functional Partners:
nadE
NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
    
 0.956
nadD
Nicotinate (nicotinamide) nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
 
 
 0.951
AKU13222.1
Pyridine nucleotide transhydrogenase, alpha subunit.
     
 0.916
AKU14175.1
NAD-dependent deacetylase.
  
 
 0.916
AKU13223.1
Pyridine nucleotide transhydrogenase, alpha subunit.
     
 0.915
AKU13221.1
Pyridine nucleotide transhydrogenase, 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.
     
 0.909
nudC
NTP pyrophosphohydrolase; Belongs to the Nudix hydrolase family. NudC subfamily.
     
 0.904
AKU12907.1
DNA repair protein; May be involved in recombinational repair of damaged DNA.
 
  
 0.813
cmk
Bifunctional 3-phosphoshikimate 1-carboxyvinyltransferase/cytidine monophosphate kinase; Catalyzes the transfer of the enolpyruvyl moiety of phosphoenolpyruvate (PEP) to the 5-hydroxyl of shikimate-3-phosphate (S3P) to produce enolpyruvyl shikimate-3-phosphate and inorganic phosphate; Belongs to the cytidylate kinase family. Type 1 subfamily.
 
  
 0.659
hrcA
Heat-inducible transcription repressor; Negative regulator of class I heat shock genes (grpE-dnaK- dnaJ and groELS operons). Prevents heat-shock induction of these operons.
       0.625
