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

Score
pyrBAspartate carbamoyltransferase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme. (304 aa)    
Predicted Functional Partners:
carA
Arginine-specific carbamoyl-phosphate synthetase (small subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme.
 
 0.999
carB
Arginine-specific carbamoyl-phosphate synthetase (large subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the CarB family.
 
 0.999
pyrR
Transcriptional attenuator and uracil phosphoribosyltransferase activity; 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; Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrR subfamily.
 
 0.999
pyrP
Uracil permease; Transport of uracil in the cell; Belongs to the xanthine/uracil permease family. Nucleobase:cation symporter-2 (NCS2) (TC 2.A.40) subfamily.
 
  
 0.999
pyrC
Dihydroorotase; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate.
 0.999
pyrAA
Pyrimidine-specific carbamoyl-phosphate synthetase (small subunit, glutaminase subunit); Evidence 2b: Function of strongly homologous gene; enzyme.
 
 0.999
pyrAB
Pyrimidine-specific carbamoyl-phosphate synthetase (large subunit); Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the CarB family.
 
 0.999
pyrK
Dihydroorotate dehydrogenase (electron transfer subunit); Responsible for channeling the electrons from the oxidation of dihydroorotate from the FMN redox center in the PyrD subunit to the ultimate electron acceptor NAD(+); Belongs to the PyrK family.
 
  
 0.999
pyrD
Dihydroorotate dehydrogenase (catalytic subunit); Catalyzes the conversion of dihydroorotate to orotate with NAD(+) as electron acceptor.
 
  
 0.999
pyrF
Orotidine 5'-phosphate decarboxylase; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP); Belongs to the OMP decarboxylase family. Type 1 subfamily.
 
  
 0.999
