Crystallization and preliminary X-ray analysis of stationary phase survival protein E (SurE) from Xylella fastidiosa in two crystal forms

The bacterium Xylella fastidiosa is a phytopathogenic organism that causes citrus variegated chlorosis, a disease which attacks economically important crops, mainly oranges. In this communication, the crystallization and preliminary X‐ray crystallographic analysis of XfSurE, a survival protein E from X. fastidiosa, are reported. Data were collected for two crystal forms, I and II, to 1.93 and 2.9 Å resolution, respectively. Crystal form I belonged to space group C2, with unit‐cell parameters a = 172.36, b = 84.18, c = 87.24 Å, α = γ = 90, β = 96.59°, whereas crystal form II belonged to space group C2, with unit‐cell parameters a = 88.05, b = 81.26, c = 72.84 Å, α = γ = 90, β = 94.76°.
