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

ppnKNAD 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. (305 aa)    
Predicted Functional Partners:
pntA
NAD(P) transhydrogenase subunit alpha; 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 AlaDH/PNT family.
     
 0.960
cobB
NAD-dependent deacetylase; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form.
  
 
 0.955
recN
DNA repair protein RecN; May be involved in recombinational repair of damaged DNA.
  
 0.949
nadR
Transcriptional regulator; Catalyzes the formation of NAD(+) from nicotinamide ribonucleotide; catalyzes the formation of nicotinamide mononucleotide from nicotinamide riboside; also has a regulatory function; Derived by automated computational analysis using gene prediction method: Protein Homology.
  
 
 0.947
pntB
Pyridine nucleotide transhydrogenase; 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.
     
 0.903
mazG
Nucleoside triphosphate hydrolase; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
  0.900
folK
7, 8-dihydro-6-hydroxymethylpterin-pyrophosphokinase; Derived by automated computational analysis using gene prediction method: Protein Homology.
      
 0.655
folC
Bifunctional folylpolyglutamate synthase/dihydrofolate synthase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the folylpolyglutamate synthase family.
     
 0.655
grpE
Molecular chaperone GrpE; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins, in association with DnaK and GrpE. It is the nucleotide exchange factor for DnaK and may function as a thermosensor. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP [...]
 
     0.643
folB
Dihydroneopterin triphosphate 2'-epimerase; Catalyzes the conversion of 7,8-dihydroneopterin to 6- hydroxymethyl-7,8-dihydropterin.
      
 0.632
