Abstract excerpt

The pyrBI operon of Escherichia coli K-12 encodes the two nonidentical subunits of the pyrimidine biosynthetic enzyme aspartate transcarbamylase (ATCase). Expression of this operon is negatively regulated by pyrimidine availability primarily through UTP-sensitive transcriptional attenuation and,...
