Ribonucleotide Reductase R2 from Escherichia coli in space group P6(1)22
OverviewOverview
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.
About this StructureAbout this Structure
2ALX is a Single protein structure of sequence from Escherichia coli with and as ligands. Active as Ribonucleoside-diphosphate reductase, with EC number 1.17.4.1 Full crystallographic information is available from OCA.
