Ribonucleotide reductase (RNR), the rate-limiting enzyme in DNA synthesis, catalyzes reduction of the different ribonucleotides to their corresponding deoxyribonucleotides. The crucial role of RNR in DNA synthesis has made it an important target for the development of antiviral and anticancer drugs. Taking account of the recent developments in this field of research, this review focuses on the role of thioredoxin and glutaredoxin systems in the redox reactions of the RNR catalysis.
核糖核苷酸还原酶(RNR)是DNA合成中的限速酶,催化不同的核糖核苷酸还原为相应的脱氧核糖核苷酸。RNR在DNA合成中的关键作用使其成为抗病毒和抗癌药物开发的重要靶点。考虑到该研究领域的最新进展,本综述重点关注硫氧还蛋白和谷氧还蛋白系统在RNR催化的氧化还原反应中的作用。
