Below is a diagram of a putative active site for Monoamine oxidase. As we learned, the purpose of tertiary structure is to form a scaffold so you can orient just a few amino acids in the right orientation to promote binding and/or catalysis. The position where this occurs is the active site. The amino acid architecture of an active site is designed to bind substrates. Amino acid side chains are capable of hydrogen bonding, ionic and hydrophobic interactions. Fill in each amino acid that you think is suitable for interacting with the part of the substrate it is closest to.
