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

pntBPyridine nucleotide transhydrogenase; Catalyzes reversible transfer of hydride ion equivalent between NAD and NADP; membrane-bound proton pump that translocates protons from cytosolic to periplasmic side of the inner membrane; forms a tetramer composed of two alpha and 2 beta subunits; AB-stereospecific enzyme; Derived by automated computational analysis using gene prediction method: Protein Homology. (458 aa)    
Predicted Functional Partners:
pntA
Forms a tetramer composed of 2 alpha subunits and 2 beta subunits in the inner membrane; involved in catalyzing transfer of hydride ion equivalents between NAD and NADP; stereospecific (AB-specific); functions as a proton pump by translocating protons from cytoplasm to periplasm; Derived by automated computational analysis using gene prediction method: Protein Homology.

KOH18762.1
Pyridine nucleotide transhydrogenase; Catalyzes the conversion of NADPH to NADH; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.916
KOH21184.1
Alanine dehydrogenase; Derived by automated computational analysis using gene prediction method: Protein Homology.
      0.912
ppnK
Inorganic polyphosphate 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.
     
 0.909
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.
    
  0.904
KOH22737.1
Nicotinic acid mononucleotide adenylyltransferase; Catalyzes the formation of deamido-NAD(+) from nicotinate ribonucleotide and ATP; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.903
cobB
NAD-dependent deacetylase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the sirtuin family. Class III subfamily.
    
  0.901
KOH23968.1
NADH pyrophosphatase; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
  0.900
der
GTP-binding protein Der; GTPase that plays an essential role in the late steps of ribosome biogenesis.
      
 0.685
prfC
Peptide chain release factor 3; Stimulates the release of release factors 1 and 2 from the ribosome after hydrolysis of the ester bond in peptidyl-tRNA has occurred; GDP/GTP-binding protein; Derived by automated computational analysis using gene prediction method: Protein Homology.
