THE FINAL REFINEMENT WAS CARRIED OUT USING SHELX-L93 WITH ALL ATOMS ANISOTROPIC. THE PRESENCE OF THE 17 IODIDE ATOMS MAKES THE APPLICATION OF THE USUAL ANALYSIS OF ERRORS NOT VALID. ONLY WHEN ANOTHER MONOCLINIC LYSOZYME STRUCTURE WITHOUT HEAVY ATOMS HAS BEEN REFINED BY THE SAME PROCEDURE WILL AN ANALYSIS BE POSSIBLE. NEVERTHELESS, A COMPARISON OF THE BOND LENGTHS BETWEEN THE TWO MOLECULES OF LYSOZYME GIVES AN AVERAGE ERROR OF 0.12 ANGSTROMS, WHICH IS IN GOOD AGREEMENT WITH THE LUZATTI ANALYSIS.
