Cu/Zn superoxide dismutase homologs participate in antiviral responses.

Superoxide dismutases (SODs) serve as the first line of defense against reactive oxygen species. Copper-zinc superoxide dismutase () is an enzyme whose activity depends on copper availability. induction is shown to be involved in the antioxidative and antiviral activity of acetylsalicylic acid in hepatitis C virus (HCV)-expressing cells.

Transient Expression of Hen Egg White Lysozyme (EWL) in Influences Plant Pathogen Infection.

Lysozyme is an enzyme that hydrolyzes bacterial cell walls, which is functional for destroying the integrity of bacteria, enhancing the activity of immune cells, participating in immune signal transmission, helping to maintain the micro-ecological balance of the gastrointestinal tract, etc. Egg white lysozyme (EWL), as one of the typical representatives of lysozyme, is the most widely used enzyme in production so far, and is also one of the most complex structures of lysozyme. EWL also helps protect plants from fungal and bacterial diseases.
