They are also called proteolytic enzymes. Proteases are classified by the amino acids or ligands that catalyze the hydrolysis reaction. For example, serine proteases contain a serine in the active site. The serine is helped by a neighboring histidine and aspartic acid. This combination is called the catalytic triad, and is conserved in all serine proteases. Serine proteases work in a two step fashion; first, they form a covalent intermediate with the protein to be cleaved; in the second step, water comes in and releases the second half of the cleaved protein. Serine proteases include a number of digestive enzymes, including Trypsin, Chymotrypsin, and Elastase. article describing Jmol to the rescue.
