Crystallization of Pleurotus ostreatus (oyster mushroom) lectin

Abstract

Crystals of Pleurotus ostreatus (oyster mushroom) lectin have been grown by the hanging-drop technique using ammonium sulfate as the precipitant at 293 K. Over a period of between two and three weeks, crystals of hexagonal bipyramidal morphology grew to maximum dimensions of 0.2 × 0.2 × 0.5 mm. The crystals belong to space group P 6 1 22 or P 6 5 22, with unit-cell parameters a = b = 155.9, c = 149.8 Å, V = 3153078 Å 3 , Z = 12 (assuming 50% solvent), and diffract to 4.1 Å at 293 K.
