1. The reduction of ribonucleotides to deoxyribonucleotides is catalyzed by ribonucleotide reductase . 2. Simultaneously deoxyribosyl analogs are formed, via the enzyme ribonucleotide reductase . 3. The glyoxylate reductase enzyme localizes to the cell cytoplasm in plants. 4. It is a molybdenum enzyme belonging to the DMSO reductase family. 5. Dihydropteridine reductase deficiency is a defect in the regeneration of tetrahydrobiopterin. 6. It is restored to the required cofactor tetrahydrobiopterin by dihydrobiopterin reductase . 7. Methionine synthase reductase regenerates a functional methionine synthase via reductive methylation. 8. Benzoyl-CoA is a substrate of benzoyl-CoA reductase . 9. There are many 5 Alpha Reductase inhibitors in natural organic forms. 10. The reaction also requires two other proteins : thioredoxin and thioredoxin reductase .
