STRINGSTRING
NRK1 protein (Saccharomyces cerevisiae) - STRING interaction network
"NRK1" - Nicotinamide riboside kinase, catalyzes the phosphorylation of nicotinamide riboside and nicotinic acid riboside in salvage pathways for NAD+ biosynthesis in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

NRK1Nicotinamide riboside kinase, catalyzes the phosphorylation of nicotinamide riboside and nicotinic acid riboside in salvage pathways for NAD+ biosynthesis; Catalyzes the phosphorylation of nicotinamide riboside (NR) and nicotinic acid riboside (NaR) to form nicotinamide mononucleotide (NMN) and nicotinic acid mononucleotide (NaMN) (240 aa)    
Predicted Functional Partners:
URH1
Uridine nucleosidase (uridine-cytidine N-ribohydrolase), cleaves N-glycosidic bonds in nucleosides; involved in the pyrimidine salvage and nicotinamide riboside salvage pathways; Also acts on cytidine (340 aa)
       
  0.995
PNP1
Purine nucleoside phosphorylase, specifically metabolizes inosine and guanosine nucleosides; involved in the nicotinamide riboside salvage pathway; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. Cleaves guanosine and inosine (By similarity) (311 aa)
     
  0.989
NPT1
Nicotinate phosphoribosyltransferase, acts in the salvage pathway of NAD+ biosynthesis; required for silencing at rDNA and telomeres and has a role in silencing at mating-type loci; localized to the nucleus; Essential for growth under anaerobic conditions (429 aa)
     
  0.989
URK1
Uridine/cytidine kinase, component of the pyrimidine ribonucleotide salvage pathway that converts uridine into UMP and cytidine into CMP; involved in the pyrimidine deoxyribonucleotide salvage pathway, converting deoxycytidine into dCMP; Catalyzes the conversion of uridine into UMP and cytidine into CMP in the pyrimidine salvage pathway (501 aa)
 
  0.972
NMA1
Nicotinic acid mononucleotide adenylyltransferase, involved in pathways of NAD biosynthesis, including the de novo, NAD(+) salvage, and nicotinamide riboside salvage pathways; Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate to form deamido- NAD(+) (NaAD). Key enzyme in both de novo and salvage pathways for NAD(+) biosynthesis. Predominantly acts in the salvage pathways via NMN (401 aa)
   
 
  0.970
POF1
Protein involved in the filamentation pathway; interacts physically with Kss1p and suppresses the filamentation defect of a kss1 deletion; Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP. Involved in the salvage pathway for NAD(+) biosynthesis via NMN (PubMed-24759102). Involved in the filamentation pathway. Suppresses the filamentation defect of a KSS1 deletion (PubMed-21460040) (258 aa)
         
  0.966
NMA2
Nicotinic acid mononucleotide adenylyltransferase, involved in de novo and salvage synthesis of NAD(+); Catalyzes the formation of NAD(+) from nicotinamide mononucleotide (NMN) and ATP (PubMed-12597897). Can also use the deamidated form; nicotinic acid mononucleotide (NaMN) as substrate to form deamido-NAD(+) (NaAD). Key enzyme in both de novo and salvage pathways for NAD(+) biosynthesis (By similarity). Predominantly acts in the salvage pathways via NMN (PubMed-11884393) (395 aa)
   
 
  0.958
BNA6
Quinolinate phosphoribosyl transferase, required for the de novo biosynthesis of NAD from tryptophan via kynurenine; expression regulated by Hst1p; Involved in the catabolism of quinolinic acid (QA) (295 aa)
         
  0.936
FUR1
Uracil phosphoribosyltransferase, synthesizes UMP from uracil; involved in the pyrimidine salvage pathway; Catalyzes the conversion of uracil and 5-phospho-alpha- D-ribose 1-diphosphate (PRPP) to UMP and diphosphate (216 aa)
   
  0.935
QNS1
Glutamine-dependent NAD(+) synthetase, essential for the formation of NAD(+) from nicotinic acid adenine dinucleotide (714 aa)
