The enzyme 6-phospho-3-hexulose isomerase (YckF) from Bacillus subtilis has been prepared and crystallized in a form suitable for X-ray crystallographic analysis. Crystals were grown by the hanging-drop method at 291 K using polyethylene glycol 2000 monomethylether as precipitant. They diffract beyond 1.7 Å using an in-house Cu Kα source and belong to either space group P6522 or P6122, with unit-cell parameters a = b = 72.4, c = 241.2 Å, and have two molecules of YckF in the asymmetric unit.
