STRINGSTRING
STRING protein interaction network
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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

pyrCDihydroorotase is involved in Pyrimidine biosynthesis. It catalyzes the reaction: (S)-dihydroorotate + H2O = N-carbamoyl-L-aspartate. It forms a homodimer and binds 2 zinc ions per subunit. Localized in the cytoplasm; High confidence in function and specificity. (420 aa)    
Predicted Functional Partners:
pyrB
Aspartate carbamoyltransferase catalyzes the conversion of aspartate and carbamoyl phosphate to carbamoylaspartate (). This is the second step in the de novo biosynthesis of pyrimidine nucleotides; Localized in the cytoplasm; High confidence in function and specificity; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
 0.999
pyrD
Dihydroorotate dehydrogenase; Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily.
 
 0.981
pyrR1
Bifunctional protein pyrR; PyrR regulates transcriptional attenuation of the pyrimidine nucleotide (pyr) operon by binding in a uridine-dependent manner to specific sites on pyr mRNA. This disrupts an antiterminator hairpin in the RNA and favors formation of a downstream transcription terminator, leading to a reduced expression of downstream genes. Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant. It forms in equilibrium a homodimer and a homohexamer. Localized in the cytoplasm; High confidence in function and specificity.
 
 
 0.942
pyrR2
Bifunctional protein PyrR; PyrR regulates transcriptional attenuation of the pyrimidine nucleotide operon by binding in a uridine-dependent manner to specific sites on pyr mRNA. This disrupts an antiterminator hairpin in the RNA and favors formation of a downstream transcription terminator, leading to a reduced expression of downstream genes. Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant. Forms momodimer and homohexamer in equilibrium. Localized in the cytoplasm; High confidence in function and specificity.
 
 
 0.929
pucH
Allantoinase is involved in purine metabolism. It catalyzes the reaction: (S)-allantoin + H2O = allantoate. Binds one zinc ion. Localized in the cytoplasm; High confidence in function and specificity.
  
  
 
0.927
carA
Carbamoyl-phosphate synthase catalyses the ATP-dependent synthesis of carbamyl-phosphate from glutamine or ammonia and bicarbonate. This important enzyme initiates both the urea cycle and the biosynthesis of arginine and/or pyrimidines. It is a heterodimer of a small and large chain. The small chain promotes the hydrolysis of glutamine to ammonia, which is used by the large chain to synthesize carbamoyl phosphate. Binds three magnesium ion as cofactor. Localized in the cytoplasm; High confidence in function and specificity; Belongs to the CarA family.
  
 0.905
carB
Carbamoyl-phosphate synthase catalyses the ATP-dependent synthesis of carbamyl-phosphate from glutamine or ammonia and bicarbonate. This important enzyme initiates both the urea cycle and the biosynthesis of arginine and/or pyrimidines. It is a heterodimer of a small and large chain. The small chain promotes the hydrolysis of glutamine to ammonia, which is used by the large chain to synthesize carbamoyl phosphate. Binds three magnesium ion as cofactor. Localized in the cytoplasm; High confidence in function and specificity.

CAZ98217.1
Membrane protein displaying a domain of unknown function DUF1550; Contains two N-terminal transmembrane helices; Localized in the cytoplasmic membrane; Family membership.
  
    0.823
pyrE
Orotate phosphoribosyltransferase; Catalyzes the transfer of a ribosyl phosphate group from 5- phosphoribose 1-diphosphate to orotate, leading to the formation of orotidine monophosphate (OMP).
 
  
 0.805
pyrF
Orotidine 5'-phosphate decarboxylase catalyzes the last step in the de novo biosynthesis of pyrimidines, the decarboxylation of Orotidine 5'-phosphate into UMP. Localized in the cytoplasm; High confidence in function and specificity; Belongs to the OMP decarboxylase family. Type 2 subfamily.
