Question

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 variety of mechanisms. These mechanisms generally utilize strategies such as 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 the human digestive tract that cleaves peptide bonds on the C-terminal side of large hydrophobic amino acids. The diagram depicts the catalytic triad of chymotrypsin, aspartate (Asp102), histidine (His57), and serine (Ser195) as well as its peptide substrate. In the molecular diagram, Ry represents a large hydrophobic amino acid and R represents other amino acids. Note that the geometry of each molecule is only roughly shown. Rį represents a large hydrophobic amino acid and R represents other amino acids in the peptide chain. HN HN 107 R ŅH
