+== Function ==
+[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.

+== Publication Abstract from PubMed ==
+A new crystal form of wild-type ribonucleotide reductase R2 from Escherichia coli was obtained. Crystals grow in space group P6(1)22 with one R2 monomer in the asymmetric unit. A twofold crystallographic symmetry axis generates the physiological dimeric form of R2. Co-crystallization with CoCl(2) or MnCl(2) results in full occupancy of the dinuclear metal site. The structure of the Mn(II)-loaded form was determined to 2.6 Angstroms resolution by molecular replacement. The crystallization conditions, backbone conformation, crystal-packing interactions and metal centers are compared with those of previously determined crystal forms.
