Crystallisation and preliminary X-ray analysis of Thermatoga mritima ribosome recycling factor

Thermotoga maritima ribosome recycling factor (RRF) is one of the proteins catalyzing the fourth step in prokaryotic protein synthesis, ribosome recycling. The RRF protein was crystallized with ammonium sulfate. Native diffraction data to 2.55 Å resolution were obtained at the MAX II synchrotron from a flash-frozen crystal at 100 K. The crystals belong to space group P41212 or P43212, with unit-cell parameters a = b = 47, c = 298 Å, and probably contain one monomer per asymmetric unit.
