title: Crystallization of phaseolin from Phaseolus vulgaris.
abstract: Three different types of crystals were grown from phaseolin, the major storage body protein from French bean. Type I crystals are cubes with space group symmetry P432, a = 67 A. Type II crystals are bipyramids with a rounded basal plane and belong to space group P2(1)2(1)2, a = 128 A, b = 136 A, and c = 162 A. Type III crystals are rhombs grown from phytic acid-free protein. The space group symmetry is P2(1)2(1)2(1), a = 113 A, b = 136 A, and c = 89 A. Both Type II and III crystals are suitable for high resolution x-ray study.
