Cupiennin
Cupiennin is a family of peptides found in the venom of the Cupiennius salei spider. These peptides are known for their potent antimicrobial and cytolytic properties, making them a subject of interest in the field of biomedical research.
Overview[edit | edit source]
Cupiennin peptides are small, cationic, and amphipathic, characteristics that allow them to interact with and disrupt cell membranes. They are primarily composed of 35-40 amino acid residues and are rich in lysine and hydrophobic amino acids.
Biological Activity[edit | edit source]
Cupiennin peptides exhibit a broad spectrum of antimicrobial activity against both Gram-positive and Gram-negative bacteria, as well as fungi. They are also cytolytic, meaning they can cause the rupture and death of various types of cells, including cancer cells.
Potential Applications[edit | edit source]
Due to their antimicrobial and cytolytic properties, Cupiennin peptides are being studied for potential use in the development of new antibiotics and cancer treatments.
