Crystallization of agglutinin from the seeds of Abrus precatorius.
Agglutinin protein purified from the seeds of Abrus precatorius has a high antitumour activity and was crystallized at room temperature with polyethylene glycol 8000 as the precipitant. The agglutinin crystal diffracted to 3.45 A and belongs to one of two possible tetragonal space groups, P4(1)2(1)2 or P4(3)2(1)2, with unit-cell parameters a = b = 141.91, c = 105.63 A. The asymmetric unit contains a heterotetrameric protein molecule of molecular weight 134 kDa and has a solvent content of approximately 38%.
