Question

Sapling Learning macmillan learring Chymotrypsin, trypsin, and elastase are digestive enzymes called serine proteases. The serine proteases differ in substrate specificity: Chymotrypsin cl chains; trypsin requires basic amino acid residues; a side chains.

Explanation / Answer

In elastase enzyme small hydrophobic amino acid side residue is fit into it. From the list of the amino acid Alanine and glycine side chain will fit . Other amino acids are having polar and bulky side chain. Answer is Alanine and glycine .
