Cysteine proteases also known as thiol proteases are enzymes that degrade proteins. These proteases share a common catalytic mechanism that involves a nucleophilic cysteine thiol in a catalytic triad or dyad.Cysteine proteases are commonly encountered in fruits including the papaya pineapple fig and kiwifruit. The proportion of protease tends to be higher when the fruit is unripe. In fact dozens of latices of different plant families are known to contain cysteine proteases.
