Intact single crystals of the enzyme lysozyme can be used to study the time-dependent, protein-directed growth of gold nanoparticles.

It was found that, if sufficient time was allowed, microcrystals developed following an induction period after initial lysozyme precipitation, even up to ionic strengths of 8 m and at acidic ph, where lysozyme is refractory to crystallization in ammonium sulfate. Lysozyme crystals have been used to grow other functional materials for catalysis and biomedical applications lysozyme is a commonly used enzyme for lysing gram. The lysozyme crystals are grown using vapour diffusion method of protein crystallization where the droplet is placed on a hydrophobic surface the droplet contains solution of protein and precipitants.

A highly crystallizable t4 lysozyme (t4l) was fused to the n-terminus of the β 2 adrenergic receptor (β 2 ar), a g-protein coupled receptor (gpcr) for catecholamines we demonstrate that the n-terminal fused t4l is sufficiently rigid relative to the receptor to facilitate crystallogenesis without.

Lysozyme is a protein belonging to a family of anti- bacterial enzymes which damage bacterial cell walls in humans, it is abundant in a number of secretions. Though normally crystallization of tetragonal lysozyme crystals may appear reproducible, the truth is, its actual crystallization process at isothermal condition can be hardly termed as reproducible according to the results of. 366 acta cryst (1994) d50, 366-369 crystallization of previously desalted lysozyme in the presence of sulfate ions by madeleine ri~s-kautt and arnaud ducruix. The possibility remains that the crystallization of lysozyme here was due to the acetate buffer present or some other (unknown) ion rather than sulfate. Lysozyme and its crystalline polymorphs: the effects of different substrates on lysozyme crystallization by dean sage and shane matthews written by dean sage.
