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

ppnKProbable 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. (283 aa)    
Predicted Functional Partners:
nadE1
NH(3)-dependent NAD(+) synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source.
    
 0.931
sir2
Transcriptional regulator Sir2 family; NAD-dependent protein deacetylase which modulates the activities of several enzymes which are inactive in their acetylated form. Deacetylates the N-terminal lysine residue of Alba, the major archaeal chromatin protein and that, in turn, increases Alba's DNA binding affinity, thereby repressing transcription; Belongs to the sirtuin family. Class U subfamily.
  
 
 0.928
nadM
Nicotinamide-nucleotide adenylyltransferase.
    
 0.920
rrnAC0727
ATP-NAD kinase.
     
 0.910
rrnAC0821
ATP-NAD kinase.
     
  0.900
kaiC2
Circadian regulator.
     
 0.777
lpdA2
Dihydrolipoamide dehydrogenase.
     
 0.666
lpdA1
Dihydrolipoamide dehydrogenase; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
     
 0.666
lpdA3
Dihydrolipoamide dehydrogenase.
     
 0.666
srp54
Signal recognition 54 kDa protein; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Belongs to the GTP-binding SRP family. SRP54 subfamily.
