== 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 anticancer agents cisplatin and carboplatin bind to histidine in a protein. This crystal structure study at data-collection temperatures of 100 and 300 K examines their relative binding affinities to a histidine side chain and the effect of a high X-ray radiation dose of up to approximately 1.8 MGy on the stability of the subsequent protein-Pt adducts. Cisplatin binding is visible at the histidine residue, but carboplatin binding is not. Five refined X-ray crystal structures are presented: one at 100 K as a reference and four at 300 K. The diffraction resolutions are 1.8, 2.0, 2.8, 2.9 and 3.5 A.
