autocatalysis A form of catalysis in which one of the products of a reaction serves as a catalyst for the reaction. Before the emergence of protein-based enzymes, which are the principle biological catalysts today, it is believed that a substance, such as RNA, may have served as both a replicator and an autocatalyzer in the first terrestrial life-forms.
