UniProt Comments
Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide. Ribonucleotide reductase (RNR) complex function is essential for efficient organellar DNA degradation in pollen. Involved in chloroplast division.
