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

ppnKAInorganic 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. It can use ATP and other nucleoside triphosphates (GTP, UTP) as well as inorganic polyphosphate (poly(P)) as a source of phosphorus. (266 aa)    
Predicted Functional Partners:
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD); Belongs to the NadD family.
  
 
 0.975
nadE
Ammonium-dependent NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
  
 
 0.965
srtN
Sirtuin NAD-dependent deacetylase; NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form; Belongs to the sirtuin family. Class U subfamily.
  
 
 0.930
ppnKB
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.
  
 
0.922
relP
(p)ppGpp synthetase; Functions as a (p)ppGpp synthase; GDP can be used instead of GTP, resulting in an increase of (p)ppGpp synthesis. The enzyme binds ATP, then GDP or GTP and catalysis is highly cooperative. In eubacteria ppGpp (guanosine 3'- diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. Probably has a minor role in the stringent response ; Belongs to the RelA/SpoT family.
  
    0.888
yjbL
Putative phosphatase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the UPF0738 family.
  
    0.750
yjbO
Pseudouridylate synthase; Evidence 2b: Function of strongly homologous gene; Product type e: enzyme.
  
  
 0.706
zwf
Glucose-6-phosphate 1-dehydrogenase; Catalyzes the oxidation of glucose 6-phosphate to 6- phosphogluconolactone.
   
  
 0.655
yjbK
Putative RNA/thiamine triphosphatase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
 
    0.653
nadC
Nicotinate-nucleotide pyrophosphorylase; Involved in the catabolism of quinolinic acid (QA).
  
  
 0.647
