title: Crystallization of Acanthamoeba profilin-I.
abstract: Profilin-I, a protein that inhibits actin polymerization in Acanthamoeba castellanii, has been crystallized in a form suitable for high resolution x-ray analysis. The crystals have the symmetry of the space group C2 with lattice constants a = 110.4 +/- 0.2, b = 31.7 +/- 0.1, c = 33.5 +/- 0.1 A, beta = 112.2 degrees. They diffract to at least 2.0-A resolution. The asymmetric unit contains one 12,800-dalton monomer of profilin-I.
