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

nadENAD(+) synthase (glutamine-hydrolyzing); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source. (538 aa)    
Predicted Functional Partners:
nadD
Nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).

gltB
Ferredoxin-dependent glutamate synthase,; Specificity unclear.
    
 0.959
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.
    
 0.956
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.
    
 0.954
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.
     
 0.935
pntAA
Probable 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.
     
 0.933
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.
