lysozyme

Examples of lysozyme in the following topics:

• Normal Eye Microbiota

  • Tears contain bactericides such as lysozyme, so that microorganisms have difficulty in surviving the lysozyme and settling on the epithelial surfaces.

• Peptidoglycan Synthesis and Cell Division

  • That is why the cell wall of Archaea is insensitive to lysozyme.
  • That is why the cell wall of Archaea is insensitive to lysozymes, which are present in human sweat and tears as part of innate immunity.

• Innate Resistance

  • Enzymes such as lysozyme and phospholipase A2 in saliva, tears, and breast milk are also antibacterials.
  • Tears contain bactericides such as lysozyme, so that microorganisms have difficulty in surviving the lysozyme and settling on the epithelial surfaces.

• Macrophages

  • Macrophages can be identified by specific expression of a number of proteins including CD14, CD40, CD11b, F4/80(mice)/EMR1(human), lysozyme M, MAC-1/MAC-3 and CD68.

• Diverse Cell Forms of Methanogens

  • These differences makes these archaea resistant to the enzyme, lysozyme, which only breaks down β (1,4) sugar linkages like those found in peptidoglycan.

• Natural Passive Immunity

  • In addition to the IgA and IgG, human milk also contains: oligosaccharides and mucins that adhere to bacteria and viruses to interfere with their attachment to host cells; lactoferrin to bind iron and make it unavailable to most bacteria; B12 binding protein to deprive bacteria of needed vitamin B12; bifidus factor that promotes the growth of Lactobacillus bifidus, normal flora in the gastrointestinal tract of infants that crowds out harmful bacteria; fibronectin that increases the antimicrobial activity of macrophages and helps repair tissue damage from infection in the gastrointestinal tract; gamma-interferon, a cytokine that enhances the activity of certain immune cells; hormones and growth factors that stimulate the baby's gastrointestinal tract to mature faster and be less susceptible to infection; and lysozyme to break down peptidoglycan in bacterial cell walls.

• X-Ray Spectra: Origins, Diffraction by Crystals, and Importance

  • X-ray diffraction from the crystal of a protein, hen egg lysozyme, produced this interference pattern.

• Phage Display

  • The new phages produce lysozyme that ruptures the cell wall of the host, leading to the release of the new phages, each ready to invade other bacterial cells.

• Digestive System: Mouth and Stomach

  • Saliva also contains immunoglobulins and lysozymes, which have antibacterial action to reduce tooth decay by inhibiting growth of some bacteria.

• Virulent Bacteriophages and T4

  • The lysozyme domain of GP5 is activated and degrades the periplasmic peptidoglycan layer.
