STRINGSTRING
GUD1 protein (Saccharomyces cerevisiae) - STRING interaction network
"GUD1" - Guanine deaminase, a catabolic enzyme of the guanine salvage pathway producing xanthine and ammonia from guanine 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

GUD1Guanine deaminase, a catabolic enzyme of the guanine salvage pathway producing xanthine and ammonia from guanine; activity is low in exponentially-growing cultures but expression is increased in post-diauxic and stationary-phase cultures; Catalyzes the hydrolytic deamination of guanine, producing xanthine and ammonia (489 aa)    
Predicted Functional Partners:
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)
   
 
  0.990
XPT1
Xanthine-guanine phosphoribosyl transferase, required for xanthine utilization and for optimal utilization of guanine; May act as a xanthine phosphoribosyltransferase involved in the synthesis of purine nucleotides. Such activity is however unclear in vivo (209 aa)
         
  0.934
HPT1
Dimeric hypoxanthine-guanine phosphoribosyltransferase, catalyzes the formation of both inosine monophosphate and guanosine monophosphate; mutations in the human homolog HPRT1 can cause Lesch-Nyhan syndrome and Kelley-Seegmiller syndrome; Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5- phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway (221 aa)
         
  0.921
URA2
Bifunctional carbamoylphosphate synthetase/aspartate transcarbamylase; catalyzes the first two enzymatic steps in the de novo biosynthesis of pyrimidines; both activities are subject to feedback inhibition by UTP; This protein is a "fusion" protein encoding three enzymatic activities of the pyrimidine pathway (GATase, CPSase, and ATCase) (2214 aa)
   
 
  0.912
APT1
Adenine phosphoribosyltransferase, catalyzes the formation of AMP from adenine and 5-phosphoribosylpyrophosphate; involved in the salvage pathway of purine nucleotide biosynthesis; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis (187 aa)
       
  0.908
APT2
Apparent pseudogene, not transcribed or translated under normal conditions; encodes a protein with similarity to adenine phosphoribosyltransferase, but artificially expressed protein exhibits no enzymatic activity; Catalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. May lack catalytic activity (181 aa)
       
  0.908
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)
   
 
  0.781
YJL213W
Protein of unknown function that may interact with ribosomes; periodically expressed during the yeast metabolic cycle; phosphorylated in vitro by the mitotic exit network (MEN) kinase complex, Dbf2p/Mob1p (331 aa)
     
  0.779
AMD1
AMP deaminase, tetrameric enzyme that catalyzes the deamination of AMP to form IMP and ammonia; may be involved in regulation of intracellular adenine nucleotide pools; AMP deaminase plays a critical role in energy metabolism (810 aa)
         
  0.761
CDC60
Cytosolic leucyl tRNA synthetase, ligates leucine to the appropriate tRNA (1090 aa)
     
 
  0.754
