Function

LYSC_CHICK Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Has bacteriolytic activity against M.luteus.[1]

Publication Abstract from PubMed

Hen egg-white lysozyme has been crystallized at slightly alkaline pH using 2-methyl-2,4-pentanediol (MPD) as the precipitant. The crystals are nearly isomorphous to crystals grown at acidic pH using sodium chloride as the precipitant. However, the growth kinetics differ markedly between the two conditions. The major reason for this is a molecule of MPD that binds tightly in between two lysozyme molecules and favors the growth of the crystals along the crystallographic c direction over growth perpendicular to it.

Crystallization, structure solution and refinement of hen egg-white lysozyme at pH 8.0 in the presence of MPD.,Weiss MS, Palm GJ, Hilgenfeld R Acta Crystallogr D Biol Crystallogr. 2000 Aug;56(Pt 8):952-8. PMID:10944331[2]
