SMU.573 from S. mutans was expressed in E. coli and crystallized. The crystals belong to space group I4 and 2.5 Å resolution diffraction data were collected at an in-house chromium radiation source. SMU.573 from Streptococcus mutans is a structurally and functionally uncharacterized protein that was selected for structural biology studies. Native and SeMet-labelled proteins were expressed with an N-His tag in Escherichia coli BL21 (DE3) and purified by Ni{sup 2+}-chelating and size-exclusion chromatography. Crystals of the SeMet-labelled protein were obtained by the hanging-drop vapour-diffusion method and a 2.5 Å resolution diffraction data set was collected using an in-house chromium radiation source. The crystals belong to space group I4, with unit-cell parameters a = b = 96.53, c = 56.26 Å, α = β = γ = 90°.
