Abstract excerpt

The purine regulon repressor, PurR, was identified as a component of the Escherichia coli regulatory system for pyrC, the gene that encodes dihydroorotase, an enzyme in de novo pyrimidine nucleotide synthesis. PurR binds to a pyrC control site that resembles a pur regulon operator and represses e...
