== Function ==
[https://www.uniprot.org/uniprot/LYSC_CHICK 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.<ref>PMID:22044478</ref>

== Publication Abstract from PubMed ==
The atomic models of native monoclinic lysozyme obtained by refinement at Bangalore and elsewhere [Young, Dewan, Nave &amp; Tilton (1993). J. Appl. Cryst. 26, 309-319] differed significantly in the flexible regions of the protein molecule. The two models were reconciled starting from regions where they were in reasonable agreement to produce an improved model which yielded an R value of 0.169 for 12 816 observed reflections in the 10-2 A resolution range. The reconciled model was compared with the structure of the 88% relative humidity form obtained through a water-mediated transformation [Madhusudan, Kodandapani &amp; Vijayan (1993). Acta Cryst. D49, 234-245]. Parts of the flexible regions of the molecule register significant movements during the transformation. The changes resulting from the transformation from the native to the low-humidity forms are pronounced in many of the side chains in the active-site region, thus indicating the relationship between hydration, mobility and enzyme action. The fact that the overall changes in molecular geometry resulting from water-mediated transformation are similar to those which occur during enzyme action, further emphasizes this relationship.
