STRINGSTRING
OXP1 protein (Saccharomyces cerevisiae) - STRING interaction network
"OXP1" - 5-oxoprolinase 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

Score
OXP15-oxoprolinase; enzyme is ATP-dependent and functions as a dimer; similar to mouse Oplah gene; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm; Catalyzes the cleavage of 5-oxo-L-proline to form L- glutamate coupled to the hydrolysis of ATP to ADP and inorganic phosphate (1286 aa)    
Predicted Functional Partners:
GSH1
Gamma glutamylcysteine synthetase catalyzes the first step in glutathione (GSH) biosynthesis; expression induced by oxidants, cadmium, and mercury (678 aa)
       
    0.964
ECM38
Gamma-glutamyltranspeptidase, major glutathione-degrading enzyme; involved in detoxification of electrophilic xenobiotics; expression induced mainly by nitrogen starvation; Catalyzes the transfer of the gamma-glutamyl moiety of glutathione (GSH) and other gamma-glutamyl compounds to amino acids and peptides. Major GSH-degrading enzyme, catalyzing the hydrolytic release of L-glutamate from GSH. Plays a role in the turnover of the vacuolar GSH, serving as an alternative nitrogen source during nitrogen starvation (660 aa)
       
  0.943
GLT1
NAD(+)-dependent glutamate synthase (GOGAT), synthesizes glutamate from glutamine and alpha-ketoglutarate; with Gln1p, forms the secondary pathway for glutamate biosynthesis from ammonia; expression regulated by nitrogen source; Forms L-glutamate from L-glutamine and 2-oxoglutarate. Represents an alternative pathway to L-glutamate dehydrogenase for the biosynthesis of L-glutamate. Participates with glutamine synthetase in ammonia assimilation processes. The enzyme is specific for NADH, L-glutamine and 2-oxoglutarate (2145 aa)
   
 
  0.883
PNC1
Nicotinamidase that converts nicotinamide to nicotinic acid as part of the NAD(+) salvage pathway, required for life span extension by calorie restriction; PNC1 expression responds to all known stimuli that extend replicative life span; Catalyzes the deamidation of nicotinamide, an early step in the NAD(+) salvage pathway. Positively regulates SIR2-mediated silencing and longevity by preventing the accumulation of intracellular nicotinamide, an inhibitor of SIR2, during times of stress. Acts also on nicotinyl hydroxamate (216 aa)
   
 
    0.847
GLN1
Glutamine synthetase (GS), synthesizes glutamine from glutamate and ammonia; with Glt1p, forms the secondary pathway for glutamate biosynthesis from ammonia; expression regulated by nitrogen source and by amino acid limitation (370 aa)
         
  0.814
PUT2
Delta-1-pyrroline-5-carboxylate dehydrogenase, nuclear-encoded mitochondrial protein involved in utilization of proline as sole nitrogen source; deficiency of the human homolog causes HPII, an autosomal recessive inborn error of metabolism (575 aa)
         
  0.808
GDH1
NADP(+)-dependent glutamate dehydrogenase, synthesizes glutamate from ammonia and alpha-ketoglutarate; rate of alpha-ketoglutarate utilization differs from Gdh3p; expression regulated by nitrogen and carbon sources (454 aa)
       
    0.800
GDH3
NADP(+)-dependent glutamate dehydrogenase, synthesizes glutamate from ammonia and alpha-ketoglutarate; rate of alpha-ketoglutarate utilization differs from Gdh1p; expression regulated by nitrogen and carbon sources (457 aa)
       
    0.800
GAD1
Glutamate decarboxylase, converts glutamate into gamma-aminobutyric acid (GABA) during glutamate catabolism; involved in response to oxidative stress (585 aa)
         
    0.800
GDH2
NAD(+)-dependent glutamate dehydrogenase, degrades glutamate to ammonia and alpha-ketoglutarate; expression sensitive to nitrogen catabolite repression and intracellular ammonia levels; NAD(+)-dependent glutamate dehydrogenase which degrades glutamate to ammonia and alpha-ketoglutarate (1092 aa)
         
    0.800
