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

pyrRPyrimidine operon regulatory 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. (178 aa)    
Predicted Functional Partners:
pyrF
Orotidine 5'-phosphate decarboxylase; Identified by match to protein family HMM PF00215; match to protein family HMM TIGR02127; Belongs to the OMP decarboxylase family. Type 2 subfamily.
  
 
 0.983
pyrB
Aspartate carbamoyltransferase; Identified by similarity to SP:P00479; match to protein family HMM PF00185; match to protein family HMM PF02729; match to protein family HMM TIGR00670; Belongs to the aspartate/ornithine carbamoyltransferase superfamily. ATCase family.
 
 
 0.974
pyrH
Uridylate kinase; Catalyzes the reversible phosphorylation of UMP to UDP.
     
 0.953
pyrC
Dihydroorotase, multifunctional complex type; Catalyzes the reversible cyclization of carbamoyl aspartate to dihydroorotate; Belongs to the metallo-dependent hydrolases superfamily. DHOase family. Class I DHOase subfamily.
 
 
 0.947
upp
Uracil phosphoribosyltransferase; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
     
 0.924
pdp
Pyrimidine-nucleoside phosphorylase; Identified by similarity to SP:P39142; match to protein family HMM PF00591; match to protein family HMM PF02885; match to protein family HMM PF07831; match to protein family HMM TIGR02644.
