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

nadKInorganic 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. (317 aa)    
Predicted Functional Partners:
nadE
NAD+ synthetase; Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source.

nadK-2
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.

EHA60388.1
PFAM: Cytidylyltransferase; KEGG: pmt:PMT1460 nicotinic acid mononucleotide adenylyltransferase; Belongs to the NadD family.
  
 
 0.886
EHA63031.1
KEGG: pmt:PMT1165 putative nicotinamide nucleotide transhydrogenase, subunit alpha 2 (A2).
     
 0.877
EHA63032.1
NAD(P)(+) transhydrogenase (AB-specific); 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.
     
 0.872
EHA63030.1
NAD(P)(+) transhydrogenase (AB-specific); KEGG: pmf:P9303_08601 putative nicotinamide nucleotide transhydrogenase, subunit alpha 1 (A1); PFAM: Alanine dehydrogenase/PNT, C-terminal; Alanine dehydrogenase/PNT, N-terminal.

EHA61792.1
PFAM: Adenylate cyclase; KEGG: pmf:P9303_26851 hypothetical protein.

ndhE
NAD(P)H-quinone oxidoreductase subunit 4L; NDH-1 shuttles electrons from an unknown electron donor, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory and/or the photosynthetic chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient. Cyanobacterial NDH-1 also plays a role in inorganic carbon-concentration.
       0.772
ndhI
NAD(P)H-quinone oxidoreductase subunit I; NDH-1 shuttles electrons from an unknown electron donor, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory and/or the photosynthetic chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient; Belongs to the complex I 23 kDa subunit family.
