  • Title: Preliminary X-ray crystallographic analysis of SMU.573, a putative sugar kinase from Streptococcus mutans.
    Author: Zhou YF, Li LF, Yang C, Liang YH, Su XD.
    Journal: Acta Crystallogr Sect F Struct Biol Cryst Commun; 2008 Jan 01; 64(Pt 1):47-9. PubMed ID: 18097102.
    Abstract:
    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 Ni2+-chelating and size-exclusion chromatography. Crystals of the SeMet-labelled protein were obtained by the hanging-drop vapour-diffusion method and a 2.5 A 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 A, alpha = beta = gamma = 90 degrees.
