title: Tetragonal crystals of canine myeloperoxidase suitable for X-ray structural analysis.
abstract: A new tetragonal crystal form of canine myeloperoxidase grown by precipitation with ammonium sulfate is described. The space group is P4(1)2(1)2 or P4(3)2(1)2 with unit cell dimensions. a = b = 133.0 A, c = 203.6 A, and a single molecule in the asymmetric unit. The crystals diffract to Bragg spacings of 2.5 A and are suitable for a medium-resolution structure determination.
