[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
Protein crystals generally are stable solid protein assemblies. Certain protein crystals are suitable for use as nanovessels for immobilizing metal complexes. Here we report the preparation of ruthenium carbonyl-incorporated cross-linked hen egg white lysozyme crystals (Ru.CL-HEWL). Ru.CL-HEWL retains a Ru carbonyl moiety that can release CO, although a composite of Ru carbonyl-HEWL dissolved in buffer solution (Ru.HEWL) does not release CO. We found that treatment of cells with Ru.CL-HEWL significantly increased nuclear factor kappa B (NF-kappaB) activity as a cellular response to CO. These results demonstrate that Ru.CL-HEWL has potential for use as an artificial extracellular scaffold suitable for transport and release of a gas molecule.
