Crystallization and preliminary X-ray analysis of apo-S100 beta and S100 beta with Ca2+.


Crystals of a bovine neurotrophic factor S100 beta with and without Ca2+ bound has been crystallized by vapor diffusion from solutions of polyethylene glycol. The crystals of S100 beta with Ca2+ bound were monoclinic and belong to space group P21 with unit cell dimensions a = 36.2 A, b = 55.63 A, c = 48.39 A and beta = 111.77 degrees. The asymmetric unit… (More)
