Thermostable enzymes are proteins that maintain their activity and structure at high temperatures. These enzymes are often derived from organisms that thrive in extreme environments, such as hot springs or deep-sea vents. Their stability allows them to function effectively in industrial processes that require elevated temperatures, making them valuable in various applications. Due to their heat resistance, thermostable enzymes are widely used in fields like biotechnology, food processing, and biofuels. They can enhance reaction rates and improve efficiency, reducing the need for harsh chemicals or conditions. This makes them essential for sustainable practices in modern industries.
