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
pyrDDihydroorotate dehydrogenase; Catalyzes the conversion of dihydroorotate to orotate with quinone as electron acceptor; Belongs to the dihydroorotate dehydrogenase family. Type 2 subfamily. (389 aa)    
Predicted Functional Partners:
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).

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.
 
 
 0.991
carB
Carbamoyl-phosphate synthase large chain; Alternative locus ID: PSB_1736.
 
 0.990
pyrB
Aspartate carbamoyltransferase; Alternative locus ID: PSB_0457; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
