What is the enzyme that breaks down keratin?

The enzyme that breaks down keratin is called keratinase. This enzyme is produced by certain microorganisms, including bacteria and fungi, which can degrade keratin, a tough and fibrous protein found in hair, nails, and the outer layer of skin. Keratinase plays a crucial role in the decomposition of keratin-rich materials, contributing to nutrient recycling in ecosystems. Its applications are also explored in industries such as waste management and bioremediation.
