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.

pyrKDihydroorotate dehydrogenase electron transfer subunit; Responsible for channeling the electrons from the oxidation of dihydroorotate from the FMN redox center in the PyrD type B subunit to the ultimate electron acceptor NAD(+). (251 aa)    
Predicted Functional Partners:
pyrD
Dihydroorotate dehydrogenase, catalytic subunit; Catalyzes the conversion of dihydroorotate to orotate.
 
 0.999
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).
  
 
 0.996
pyrC
Dihydroorotase; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate; Belongs to the metallo-dependent hydrolases superfamily. DHOase family. Class I DHOase subfamily.

 0.808
pyrP
Putative uracil permease.
  
  
 0.742
pyrR-2
Pyrimidine operon regulatory protein; Also displays a weak uracil phosphoribosyltransferase activity which is not physiologically significant; Belongs to the purine/pyrimidine phosphoribosyltransferase family. PyrR subfamily.
