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

Score
ppnKInorganic polyphosphate kinase; Catalyzes the phosphorylation of NAD to NADP; Derived by automated computational analysis using gene prediction method: Protein Homology. (292 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.
     
 0.885
nadR_2
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.
  
 
 0.880
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.
     
 0.861
nadE
NAD synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses ammonia as a nitrogen source; Belongs to the NAD synthetase family.
    
 0.814
cobB_1
NAD-dependent deacetylase; Modulates the activities of several enzymes which are inactive in their acetylated form; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the sirtuin family. Class III subfamily.
  
 
 0.776
ybeB
Ribosome-associated 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.
    
 0.766
sthA
Pyridine nucleotide transhydrogenase; Conversion of NADPH, generated by peripheral catabolic pathways, to NADH, which can enter the respiratory chain for energy generation; Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
     
 0.734
coaD
Phosphopantetheine adenylyltransferase; Reversibly transfers an adenylyl group from ATP to 4'- phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate. Belongs to the bacterial CoaD family.
    
 0.699
nudC
NADH pyrophosphatase; Can catalyze hydrolysis of broad range of dinucleotide pyrophosphates but prefers reduced form of NADH; requires divalent metal ions such as magnesium and manganese and produces two mononucleoside 5'-phosphates; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.698
mazG
Nucleoside triphosphate hydrolase; Functions in degradation of stringent response intracellular messenger ppGpp; in Escherichia coli this gene is co-transcribed with the toxin/antitoxin genes mazEF; activity of MazG is inhibited by MazEF in vitro; ppGpp inhibits mazEF expression; MazG thus works in limiting the toxic activity of the MazF toxin induced during starvation; MazG also interacts with the GTPase protein Era; Derived by automated computational analysis using gene prediction method: Protein Homology.
