	Lysozyme - Wikipedia, the free encyclopedia
		Lysozyme is an enzyme (EC 3.2.1.17), commonly referred to as the "body's own antibiotic" since it kills bacteria.
		Lysozyme serves as an unspecific innate opsonin by binding to the bacterial surface to reduce the negative charge and facilitate phagocytosis of this bacterium before opsonins from the acquired immune systems enter the scene.
		Lysozyme levels in the blood are often increased in sarcoidosis.

		Lysozyme damages the cell walls of bacteria and fungi by hydrolyzing the [beta]1-4 glycosidic bond between N-acetylmuramic acid and N-acetylglucosamine, which are structural components of bacterial peptidoglycan and fungal chitin, respectively.
		Lysozyme M is the major form expressed in murine epithelial cells and leukocytes, and lysozyme P is normally limited to the Paneth cells of the small intestine (8, 9).
		Increased inflammation in lysozyme M-deficient mice in response to Micrococcus luteus and its peptidoglyean.

	WINE BUSINESS Printer version
		Lysozyme is a protein derived from egg whites, with a lytic activity towards Gram-positive bacteria.
		Until recently, the use of lysozyme was mostly recommended to delay or block malolactic fermentation, prevent unwanted bacterial growth during storage or ageing, and inhibit further bacterial spoilage in the case of stuck or sluggish fermentation.
		The prophylactic use of lysozyme is especially recommended in wines of high pHs; wines with a history of stuck or sluggish fermentation or a history of high levels of volatile acidity and off-flavors, as well as wines or wineries that have frequent contamination problems with Lactobacilli or Pediococci", says Petersen.

	BYO - Lysozyme
		Lysozyme is found abundantly in nature and is produced by bacteria, fungi, plants, birds, and mammals.
		Although lysozyme is found in high concentrations in human tears, commercial lysozyme is made from hen egg whites.
		Lysozyme is effective against Gram positive bacteria (all lactic acid bacteria) due to its ability to specifically break down the cell wall structure of those microorganisms.

	Lysozyme, Serum
		Lysozyme, an hydrolytic enzyme - a bacteriolytic glycosidase, when present in large amounts may appear as a far cathodal migrating ("cationic") band on serum or urine protein electrophoresis.
		Serum lysozyme has been shown to be elevated in a number of conditions, including tuberculosis and sarcoidosis as well as leukemia.
		Utilizing a turbidimetric method for measurement of serum lysozyme activity, there was evidence that such an assay was useful in differentiating infection from rejection in transplant recipients.

		Lysozyme comes from many plant and animal sources, but is especially plentiful in hen egg whites.
		Each egg white had a different mass, and since the amount of lysozyme in each egg white is proportional to it's mass, it is necessary to compare the amounts of lysozyme extracted in terms of percentages.
		Work with lysozyme is constantly being completed because of how commercially useful it is. One current study is interested in enabling lysozyme to work on gram-negative bacteria as well as those that are gram-positive.

		Lysozyme is a globular protein containing 129 amino acids that was discovered in 1922 by Alexander Flemming by accident (5).
		Lysozyme was first introduced to the author the summer of 1998 in a biochemical laboratory at Bowling Green State University (BGSU).
		At first all lysozyme molecules are available to bind to substrate; but as the enzyme (lysozyme) activities begin to "fill-up" with substrate (Ml), the observed effect is a leveling off of enzyme activity.

	Title of Invention: Use of lysozyme gene structures in plants to increase resistance
		Lysozyme genes are understood as meaning any nucleic acid (DNA) which, after having been transcribed into RNA and translated into protein, effects (in a suitable environment) the formation of an enzyme which has the known properties of lysozymes.
		Preferred lysozyme gene structures which can be used according to the invention consist of, or contain, chimeric gene fusions which, in addition to the lysozyme gene(s), contain the TR promoter and the signal peptide sequence of barley alpha-amylase, as they occur in plasmid pSR 2-4.
		The lysozyme genes can be completely present in the gene structures, that is to say with their natural regulatory parts (in particular promoters) or only in the form of the structural genes which encode the protein lysozyme.
