STRINGSTRING
CPA1 protein (Saccharomyces cerevisiae) - STRING interaction network
"CPA1" - Small subunit of carbamoyl phosphate synthetase, which catalyzes a step in the synthesis of citrulline, an arginine precursor 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

CPA1Small subunit of carbamoyl phosphate synthetase, which catalyzes a step in the synthesis of citrulline, an arginine precursor; translationally regulated by an attenuator peptide encoded by YOR302W within the CPA1 mRNA 5’-leader (411 aa)    
Predicted Functional Partners:
CPA2
Large subunit of carbamoyl phosphate synthetase, which catalyzes a step in the synthesis of citrulline, an arginine precursor (1118 aa)
  0.999
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
ARG3
Ornithine carbamoyltransferase; also known as carbamoylphosphate-L-ornithine carbamoyltransferase; catalyzes the biosynthesis of the arginine precursor citrulline (338 aa)
 
 
  0.995
ARG1
Arginosuccinate synthetase, catalyzes the formation of L-argininosuccinate from citrulline and L-aspartate in the arginine biosynthesis pathway; potential Cdc28p substrate; Catalyzes the eighth step in arginine biosynthesis. Also has a catabolic function as the first enzyme of citrulline utilization as nitrogen source via arginine and the reactions involved in the arginase pathway (420 aa)
   
 
  0.986
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)
   
 
  0.985
GUA1
GMP synthase; highly conserved enzyme that catalyzes the second step in the biosynthesis of GMP from inosine 5’-phosphate (IMP); transcription is not subject to regulation by guanine but is negatively regulated by nutrient starvation; reduction-of-f /.../n mutation gua1-G388D causes changes in cellular guanine nucleotide pools, defects in general protein synthesis, and impaired translation of GCN4 mRNA (525 aa)
   
   
  0.977
YOR302W
CPA1 uORF, Arginine attenuator peptide, regulates translation of the CPA1 mRNA; Arginine attenuator peptide (AAP) that has a regulatory role in the production of arginine-specific carbamoyl phosphate synthetase. Encoded by an upstream open reading frame (uORF) within the 5’-leader region of arginine-specific carbamoyl phosphate synthetase small chain (CPA1) mRNA, it attenuates the translation of the downstream CPA1 ORF. In the presence of high concentrations of arginine, ribosomes translating the uORF encoding AAP stall at the termination codon, resulting in reduced translation from th [...] (25 aa)
     
   
  0.976
GFA1
Glutamine-fructose-6-phosphate amidotransferase, catalyzes the formation of glucosamine-6-P and glutamate from fructose-6-P and glutamine in the first step of chitin biosynthesis; Involved in amino sugar synthesis (formation of chitin, supplies the amino sugars of asparagine-linked oligosaccharides of glycoproteins) (717 aa)
     
  0.962
DAL1
Allantoinase, converts allantoin to allantoate in the first step of allantoin degradation; expression sensitive to nitrogen catabolite repression; Utilization of purines as secondary nitrogen sources, when primary sources are limiting (460 aa)
 
 
  0.961
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)
