Question

Ribonucleotide reductase controls the synthesis of deoxyribonucleotides and the balance of nucleotides in the cell. The R1 subunit of ribonucleotide reductase contains two allosteric sites, one that regulates the overall enzyme activity and another that regulates the substrate specificity of the enzyme.

Select the molecules that bind the site regulating overall ribonucleotide reductase activity.

A. GTP
B. GTP
C. МАТР
D. DATP

Answer 1

ATP and dATP

Step-by-step explanation:

In the R1 subunit of ribonucleotide reductase, molecules that binds the site regulating overall ribonucleotide reductase activity include both ATP and dATP. In addition, binding of ATP can activate ribonucleotide reductase and the binding of dATP deactivates ribonucleotide reductase.
