'D) What are the different substrate specificities of elastase, trypsin, and chymotrypsin? And, why, from a structural standpoint; do elastase, trypsin, and chymotrypsin have different substrate specificities?'
Muhammad A.
Chymotrypsin, trypsin, and elastase are digestive enzymes called serine proteases. The serine proteases differ in substrate specificity: Chymotrypsin cleaves peptide bonds after aromatic or bulky hydrophobic side chains, trypsin requires basic amino acid residues, and elastase cleaves bonds following small uncharged side chains. A chart of amino acids is available for your reference. Determine which specificity pocket is part of each enzyme.
