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

pyrRPyrimidine operon attenuation protein uracil phosphoribosyltransferase; 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. (174 aa)    
Predicted Functional Partners:
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.
  
 
 0.990
pyrB
Aspartate carbamoyltransferase catalytic subunit; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
 
 0.987
pyrC
Dihydroorotase; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate; Belongs to the metallo-dependent hydrolases superfamily. DHOase family. Class I DHOase subfamily.
 
 
 0.983
pyrP
Uracil permease.
  
  
 0.962
pyrAB
Carbamoyl-phosphate synthase large chain.
  
  
 0.947
udk
Uridine kinase.
     
 0.929
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP.
     
 0.927
upp
Uracil phosphoribosyl transferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
     
 0.927
pdp
Pyrimidine-nucleoside phosphorylase.
     
 0.914
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).
