Artificial enzymes, also known as artificial catalytic agents, are synthetic molecules designed to mimic the functions of natural enzymes. These molecules are typically designed through rational design or directed evolution to catalyze specific chemical reactions with high efficiency and selectivity. Artificial enzymes hold great potential for various applications in biotechnology, medicine, and environmental science, as they can be tailored to perform specific functions that are not possible with natural enzymes. Researchers are actively exploring different strategies to create artificial enzymes that can effectively catalyze a wide range of reactions and offer new opportunities for chemical synthesis and drug discovery.
