Crystallization and preliminary X-ray analysis of Escherichia coli RNase G

Full-length E. coli RNase G was overexpressed, purified and crystallized. Diffraction data were collected to a resolution of 3.4 Å. The homologous RNases RNase E and RNase G are widely distributed in bacteria and function in many important physiological processes, including mRNA degradation, rRNA maturation and so on. In this study, the crystallization and preliminary X-ray analysis of RNase G from Escherichia coli is described. Purified recombinant E. coli RNase G, which has 497 amino acids, was crystallized in the cubic space group F432, with unit-cell parameters a = b = c = 219.84 Å. X-ray diffraction data were collected to a resolution of 3.4 Å
