Lysozyme, known for breaking down bacterial cell walls, also binds to DNA and RNA. This interaction may explain its "killer protein" activity against the AIDS virus, opening new therapeutic research avenues.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Virology

Background:

  • Lysozyme is recognized for its antibacterial properties, specifically its ability to hydrolyze bacterial cell walls.
  • Structural similarities between lysozyme and histones suggest potential interactions with nucleic acids.

Purpose of the Study:

  • To investigate the potential biological function of lysozyme in binding to nucleic acids.
  • To explore lysozyme's interactions with DNA and RNA.

Main Methods:

  • Gel electrophoresis to detect binding.
  • Enzyme activity assays.
  • Coprecipitation studies to confirm interactions.

Main Results:

  • Demonstrated binding of lysozyme to both DNA and RNA.

  • Preliminary evidence supports nucleic acid interaction as a function of lysozyme.

    • Conclusions:

    • Lysozyme exhibits binding capabilities towards nucleic acids (DNA and RNA).
    • This nucleic acid binding function may underlie its previously reported antiviral activity against the Human Immunodeficiency Virus (HIV).
    • Suggests a novel therapeutic strategy for Acquired Immunodeficiency Syndrome (AIDS) research.
