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

pntAAProbable NAD(P) transhydrogenase, subunit alpha part 1. Homology to pntAA of R. rubrum of 44% (sprot|PNAA_RHORU). The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane. Tirfam: pntA: NAD(P) transhydrogenase alpha subunit Pfam: Alanine dehydrogenase/pyridine nucleotide dehydrogenase no signal peptide no TMHs; High confidence in function and specificity. (373 aa)    
Predicted Functional Partners:
pntB
Probable NAD(P) transhydrogenase, subunit beta; 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.
 0.999
pntAB
Conserved hypothetical NAD(P) transhydrogenase,subunit alpha part 2. Homology to pntA of X. axonopodis of 74% (trembl|Q8PNW6). The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane. 3 TMHs no signal peptide; High confidence in function and specificity.
 
 
 0.996
ppnK
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.
     
 0.951
nadE
NAD(+) synthase (glutamine-hydrolyzing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.
     
 0.933
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
     
 0.927
npd2
NAD-dependent deacetylase 2 (EC 3.5.1.-) (Regulatory protein SIR2 homolog 2). Modulates the activities of several enzymes which are inactive in their acetylated form. Similar to SWISSPROT: sprot|NPD2_PSEAE (50% Pseudomonas aeruginosa, Npd2) / sprot|NPD1_ARCFU (33% Archaeoglobus fulgidus, NpdA) InterPro: IPR003000 SIR2. Pfam: PF02146 Sir2 family; High confidence in function and specificity.
     
 0.894
rpoC
DNA-directed RNA polymerase; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates.
   
    0.644
ilvC
IlvC protein; Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate.

lpdA
Dihydrolipoamide dehydrogenase. Homology to lpdA of N. meningitides of 70% (trembl|Q59099). THE BRANCHED-CHAIN ALPHA-KETO DEHYDROGENASE COMPLEX CATALYZES THE OVERALL CONVERSION OF ALPHA-KETO ACIDS TO ACYL-COA AND CO(2). IT CONTAINS MULTIPLE COPIES OF 3 ENZYMATIC COMPONENTS: BRANCHED-CHAIN ALPHA-KETO ACID DECARBOXYLASE (E1) LIPOAMIDE ACYLTRANSFERASE (E2) AND LIPOAMIDE DEHYDROGENASE (E3) (BY SIMILARITY). InterPro: FAD-dependent pyridine nucleotide-disulphide oxidoreductase (IPR001327); Pyridine nucleotide-disulphide oxidoreductase, classI (IPR001100); biotin/Lipoyl attachment (IPR000089) [...]
