Serine, histidine, and aspartate are often found in the active sites of enzymes due to their ability to participate in catalysis through their side chain functionalities. Serine and aspartate can act as nucleophiles or electrophiles, and histidine can serve as a proton donor or acceptor, making them versatile in enzyme catalysis.
