Sh. Liaw et al., Crystallization and preliminary X-ray diffraction analysis of group 5 miteallergen from Dermatophagoides pteronyssinus, J STRUCT B, 123(3), 1998, pp. 265-268
Crystals of the 14-kDa group 5 allergen from Dermatophagoides pteronyssinus
(Der p 5) have been obtained at low pH and diffract to 3-Angstrom resoluti
on using a conventional x-ray source. The crystals belong to tetragonal spa
ce group P4(1)2(1)2 or P4(3)2(1)2, with unit cell parameters a = b = 114 An
gstrom and c = 234 Angstrom. A self-rotation search revealed a 432 point sy
mmetry and thus suggested 96 molecules in one unit cell, hence 12 monomers
in each asymmetric unit. (C) 1998 Academic Press.
