Depicted below are a peptide substrate and the three catalytic residues within the chymotrypsin active site Note that the 2-dimensional geometry is only roughly shown. R1 represents a large hydrophobic amino acid and R represents other amino acids. The R groups of the catalytic triad of aspartate (Asp102), serine (Ser195), and histidine (His57) are shown.

Under typical conditions, many essential biochemical reactions
proceed so slowly that life could not exist without the presence of
enzymes. Enzymes increase reaction rates through a wide variety of
mechanisms. These mechanisms generally utilize the following
strategies: improving the nucleophiles and electrophiles present in
the catalytic R groups or substrates; stabilizing the extra
electron density of the leaving group; and stabilizing transition
states. Proteases are enzymes that break down proteins by
hydrolyzing peptide bonds. Chymotrypsin is a protease found in...
