Chitin is an important component in cell walls in fungi; a chitin-binding protein can disrupt chitin's normal function, and destabilize the cell wall of a fungal cell. It's not uncommon for plants to use chitin-binding proteins as defense mechanisms against fungus, and Batista et al. found the chitin-binding protein Mo-CBP3 in Moringa oleifera, commonly known as the drumstick tree or the horseradish tree. After discovering its antifungal effects, this paper focuses on the antimicrobial protein's mechanism of action, structural features and stability of Mo-CBP3.
