Lysozyme is a glycosidase which hydrolyzes the ß 1,4 glycosidic bond between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in the bacterial peptidoglycan [1].

Lysozyme can be utilized as model protein in crystallization experiments and X-ray structure analysis.

Crystals can be grown using the sitting drop, hanging drop or microbatch method.
Following crystallization conditions are suggested for lysozyme crystal growth:

  • 0.7 - 1.5 M Sodium Chloride, 100 mM Sodium Acetate pH 4.0 - 4.8 [2]
  • 10 % w/v Sodium Chloride, 5% v/v Propanol [2]
  • 0.44 M Sodium Nitrate, 100 mM Sodium Acetate pH 4.6 [2]
