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

ppnK2ATP-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. (265 aa)    
Predicted Functional Partners:
ppnK1
Probable 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.
  
  
0.677
argB
N-acetylglutamate 5-phosphotransferase; Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate; Belongs to the acetylglutamate kinase family. ArgB subfamily.
      
 0.674
nadD
Nicotinate-nucleotide adenylyltransferase NadD; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
  
 
 0.649
nadE
NH3-dependent NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
    
 0.644
npdA
NdpA; 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.
  
 
 0.619
ahrC
Transcriptional regulator; Regulates arginine biosynthesis genes and activates arginine deiminase pathway genes; Belongs to the ArgR family.
  
  
 0.571
argR
Transcriptional regulator of arginine metabolism expression; Regulates arginine biosynthesis genes.
  
  
 0.571
sppA
Signal peptide peptidase.
       0.565
yteJ
Conserved membrane protein YteJ.
  
    0.561
rsfS
Iojap-related protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
