by proteases having a long binding cleft or tunnel with several pockets that bind to specified residues. For example, TEV protease is specific for the sequence ...ENLYFQ\S... ('\'=cleavage site).

Degradation and autolysis

Proteases, being themselves proteins, are cleaved by other protease molecules, sometimes of the same variety. This acts as a method of regulation of protease activity. Some proteases are less active after autolysis (e.g. TEV protease)
