Role of the purine repressor in the regulation of pyrimidine gene expression in Escherichia coli K-12.

Journal of bacteriology - 1 Jun 1990

Abstract excerpt

The pyrC and pyrD genes of Escherichia coli K-12 encode the pyrimidine biosynthetic enzymes dihydroorotase and dihydroorotate dehydrogenase, respectively. A highly conserved sequence in the promoter regions of these two genes is similar to the pur operator, which is the binding site for the purin...
