STRINGSTRING
URA4 protein (Saccharomyces cerevisiae) - STRING interaction network
"URA4" - Dihydroorotase, catalyzes the third enzymatic step in the de novo biosynthesis of pyrimidines, converting carbamoyl-L-aspartate into dihydroorotate 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

URA4Dihydroorotase, catalyzes the third enzymatic step in the de novo biosynthesis of pyrimidines, converting carbamoyl-L-aspartate into dihydroorotate (364 aa)    
Predicted Functional Partners:
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)
   
 
  0.999
URA1
Dihydroorotate dehydrogenase, catalyzes the fourth enzymatic step in the de novo biosynthesis of pyrimidines, converting dihydroorotic acid into orotic acid; Catalyzes the conversion of dihydroorotate to orotate with fumarate as the electron acceptor. Molecular oxygen can replace fumarate in vitro. Does not use oxaloacetate or NAD or NADP as electron acceptors (314 aa)
   
 
  0.999
URA5
Major orotate phosphoribosyltransferase (OPRTase) isozyme that catalyzes the fifth enzymatic step in de novo biosynthesis of pyrimidines, converting orotate into orotidine-5’-phosphate; minor OPRTase encoded by URA10; Catalyzes the transfer of a ribosyl phosphate group from 5-phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP) (226 aa)
   
   
  0.977
URA3
Orotidine-5’-phosphate (OMP) decarboxylase, catalyzes the sixth enzymatic step in the de novo biosynthesis of pyrimidines, converting OMP into uridine monophosphate (UMP); converts 5-FOA into 5-fluorouracil, a toxic compound (267 aa)
     
 
  0.959
AAT2
Cytosolic aspartate aminotransferase involved in nitrogen metabolism; localizes to peroxisomes in oleate-grown cells; Plays a key role in amino acid metabolism (418 aa)
     
 
  0.954
PPR1
Zinc finger transcription factor containing a Zn(2)-Cys(6) binuclear cluster domain, positively regulates transcription of genes involved in uracil biosynthesis; activity may be modulated by interaction with Tup1p; Positive regulator of URA1 and URA3 expression (904 aa)
     
   
  0.946
ADE6
Formylglycinamidine-ribonucleotide (FGAM)-synthetase, catalyzes a step in the ’de novo’ purine nucleotide biosynthetic pathway; Phosphoribosylformylglycinamidine synthase involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate (By similarity) (1358 aa)
     
   
  0.931
SIR3
Silencing protein that interacts with Sir2p and Sir4p, and histone H3 and H4 tails, to establish a transcriptionally silent chromatin state; required for spreading of silenced chromatin; recruited to chromatin through interaction with Rap1p; The proteins SIR1 through SIR4 are required for transcriptional repression of the silent mating type loci, HML and HMR. The proteins SIR2 through SIR4 repress mulitple loci by modulating chromatin structure. Involves the compaction of chromatin fiber into a more condensed form (978 aa)
     
   
  0.919
CST6
Basic leucine zipper (bZIP) transcription factor of the ATF/CREB family, proposed to be a regulator of oleate responsive genes; involved in utilization of non-optimal carbon sources and chromosome stability; Transcriptional activator of promoters containing ATF/CREB sites. Can independently stimulate transcription through ATF/CREB sites. Important for a variety of biological functions including growth on non-optimal carbon sources (587 aa)
     
   
  0.912
MON2
Peripheral membrane protein with a role in endocytosis and vacuole integrity, interacts with Arl1p and localizes to the endosome; member of the Sec7p family of proteins; Required for traffic between late Golgi and early endosomes. Required for endocytosis and maintenance of vacuolar structure (1636 aa)
