Endopolygalacturonase SE1 from Trichosporon penicillatum has been crystallized by the hanging-drop method of vapour diffusion using ammonium sulfate as a precipitant. The crystals belong to the hexagonal space group P61 or P65, with unit-cell parameters a = b = 135.0, c = 70.7 Å, γ = 120°. The calculated VM based on one molecule per asymmetric unit is 3.09 Å3 Da−1. A native data set from a crystal has been collected to 2.0 Å resolution on a Cu Kα rotating-anode X-ray source.
