'''Ribonucleotide Reductase R2 from Escherichia coli in space group P6(1)22'''<br />
'''Ribonucleotide Reductase R2 from Escherichia coli in space group P6(1)22'''<br />


==Overview==
==Overview==
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.
