Sapling Learning proteasee Chymotrypsin trypsin and elastase

Sapling Learning proteasee Chymotrypsin, trypsin, and elastase are digestive enzymes called serine proteases. The serine sid differ in substrate cleaves peptide bonds after aromatic or bulky hydrophobic chains; trypsin requires basic amino acid residues: and elastase cleaves bonds following small unc side chains. A chart of amino acids can be found bere. below The specificity pockets (substrate binding sites) of each of the serine proteases are drawn amino (b) Which of the following (a) Determine which specificity pocket is a part of each enzyme. Move each specificity pocket, below, to the proper bin. specificity pocket of trypsin? Select Note: If you answer part (a) incorrectly, a single red X will appear all the amino acids that fit.

Solution

Ans:a)Serine proteases substrate binding sites

First bin-Elastase (Valine and threonine)

Second bin-Chymotripsin (Ser)

Third bin-Trypsin (Aspergine)

b) Lysine, arginine and aspartate
