Crystallization and preliminary X-ray diffraction studies of psoriasin.
Crystals of psoriasin, a protein related to the skin disease psoriasis, have been grown in two different crystal forms. Form I represents the protein in the Ca(2+)-bound form, and form II represents the protein in the Zn(2+)- and Ca(2+)-bound form. The crystals of form I are orthorhombic belonging to the space group P2(1)2(1)2(1) with cell parameters a = 52.15, b = 56.67 and c = 76.38 A and diffract to 2.4 A. The crystals of form II are tetragonal and belong to the space group P4(1(3))2(1)2 with cell parameters a = b = 51.86, c = 115.93 A and diffract to 2.0 A.
