additional information | the enzyme reduces ribonucleotides at a low basal rate. Reduction is stimulated up to 10fold by an appropriate modulator (dGTP for ATP reduction, ATP for CTP and UTP reduction, and dlTP for GTP reduction). The enzyme has one class of sites that binds ATP and dATP and regulates pyrimidine ribonucleotide reduction, and another class that binds dATP, dGTP, and dTTP and regulates purine ribonucleotide reduction | Escherichia coli | ? | - |
