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

pyrCDihydro-orotase; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate; Belongs to the metallo-dependent hydrolases superfamily. DHOase family. Class II DHOase subfamily. (348 aa)    
Predicted Functional Partners:
pyrD
Dihydro-orotate oxidase, FMN-linked; Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor.
 
 
 0.999
pyrB
Aspartate carbamoyltransferase, catalytic subunit; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
   
 
 0.997
pyrI
Aspartate carbamoyltransferase, regulatory subunit; Involved in allosteric regulation of aspartate carbamoyltransferase; Belongs to the PyrI family.
   
 
 0.973
pyrF
Orotidine-5'-phosphate decarboxylase; Catalyzes the decarboxylation of orotidine 5'-monophosphate (OMP) to uridine 5'-monophosphate (UMP).
   
  
 0.910
carB
Carbamoyl-phosphate synthase large subunit; Protein involved in arginine biosynthetic process and pyrimidine nucleotide biosynthetic process; Belongs to the CarB family.
   
  
 0.904
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); Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrE subfamily.
 
 
 0.897
codA
Cytosine/isoguanine deaminase; Catalyzes the hydrolytic deamination of cytosine to uracil. Is involved in the pyrimidine salvage pathway, which allows the cell to utilize cytosine for pyrimidine nucleotide synthesis. Is also able to catalyze deamination of isoguanine, a mutagenic oxidation product of adenine in DNA, and of isocytosine. To a lesser extent, also catalyzes the conversion of 5-fluorocytosine (5FC) to 5-fluorouracil (5FU); this activity allows the formation of a cytotoxic chemotherapeutic agent from a non-cytotoxic precursor. Belongs to the metallo-dependent hydrolases supe [...]
  
  
 0.881
purB
Adenylosuccinate lyase; Protein involved in purine nucleotide biosynthetic process; Belongs to the lyase 1 family. Adenylosuccinate lyase subfamily.
   
  
 0.868
pntA
Pyridine nucleotide transhydrogenase, alpha subunit; The transhydrogenation between NADH and NADP is coupled to respiration and ATP hydrolysis and functions as a proton pump across the membrane; Belongs to the AlaDH/PNT family.
   
  
 0.855
codB
Cytosine transporter; Required for cytosine transport into the cell; Belongs to the purine-cytosine permease (2.A.39) family.
