[[ | [[https://www.uniprot.org/uniprot/RIR1_ECOLI RIR1_ECOLI]] 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. It also provides redox-active cysteines. [[https://www.uniprot.org/uniprot/RIR2_ECOLI RIR2_ECOLI]] Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R2 contains the tyrosyl radical required for catalysis. | ||
