Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen.ikewise, catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert approximately 5 million molecules of hydrogen peroxide to water and oxygen each second.
Catalase (like many enzymes) has a specific function. This is because of the unique shape of the catalase molecule. Its shape allows the enzyme to bond with a specific substrate (such as hydrogen peroxide). A substrate is the compound with which an enzyme bonds. Think of it as a lock and key. In our example, catalase represents the lock, and the hydrogen peroxide represents the key.
