ribonucleoside diphosphate reductase
ri·bo·nu·cleo·side di·phos·phate re·duc·tase (ri″bo-nooґkle-o-sīd″ di-fosґfāt re-dukґtās) [EC 1.17.4.1] an enzyme of the oxidoreductase class that catalyzes the formation of 2′-deoxyribonucleotides from the corresponding ribonucleoside diphosphates using NADPH as the ultimate electron donor. The deoxyribonucleoside diphosphates are used in DNA synthesis. Called also ribonucleotide reductase.
