Cloning, purification and crystallographic analysis of a hypothetical protein, BPSL1549, from Burkholderia pseudomallei

Burkholderia pseudomallei BPSL1549, a putative protein of unknown function, has been overexpressed in Escherichia coli, purified and subsequently crystallized by the hanging-drop vapour-diffusion method using PEG as a precipitant to give crystals with overall dimensions of 0.15 × 0.15 × 0.1 mm. Native data were collected to 1.47 Å resolution at the European Synchrotron Radiation Facility (ESRF). The crystals belonged to space group P2₁2₁2₁, with unit-cell parameters a = 37.1, b = 45.4, c = 111.9 Å and with a single polypeptide chain in the asymmetric unit.
