title: Crystallization and preliminary X-ray diffraction analysis of group 5 mite allergen from Dermatophagoides pteronyssinus.
abstract: Crystals of the 14-kDa group 5 allergen from Dermatophagoides pteronyssinus (Der p 5) have been obtained at low pH and diffract to 3-A resolution using a conventional x-ray source. The crystals belong to tetragonal space group P41212 or P43212, with unit cell parameters a = b = 114 A and c = 234 A. A self-rotation search revealed a 432 point symmetry and thus suggested 96 molecules in one unit cell, hence 12 monomers in each asymmetric unit.
