  • Title: Compressibility of lysozyme protein crystals by X-ray diffraction.
    Author: Katrusiak A, Dauter Z.
    Journal: Acta Crystallogr D Biol Crystallogr; 1996 May 01; 52(Pt 3):607-8. PubMed ID: 15299694.
    Abstract:
    Single-crystal high-pressure X-ray diffraction studies on the protein crystals of orthorhombic and tetragonal hen egg-white lysozyme polymorphs were carried out using a Merrill-Bassett diamond-anvil cell, image-plate detector and synchrotron radiation. The orthorhombic crystal has been squeezed to 85.5% of its ambient pressure volume at about 1.0 GPa; the crystal compresses anisotropically, and neither a glass transition or denaturation was observed. The tetragonal polymorph of lysozyme undergoes amorphization at pressures about 0.2 GPa.
