Cytochromes P450 (CYPs) are enzymes that utilize heme as a cofactor to catalyze monooxygenase reactions. They belong to a superfamily of enzymes that have been identified in all kingdoms of life, including plants, animals, fungi, protists, bacteria, archaea, and even viruses. P450s are known for their remarkable ability to catalyze over 20 types of oxido-reduction reactions, making them Nature's Most Versatile Biological Catalyst. However, despite the existence of more than 300,000 P450 genes in different databases, less than 0.2% of them have been functionally characterized.
    Here, we present the P450Reaction database, a manually curated resource of literature-supported reactions catalyzed by P450s. This database currently catalogs over 1,600 reactions involving about 600 P450s from a wide range of over 200 species, including plants, animals, fungi, bacteria, and archaea.
    Our aim is to offer a useful platform for research in metabolism, synthetic biology, pharmacology, and enzyme engineering. By providing a comprehensive and reliable resource of P450 reactions, we hope to facilitate the discovery of new P450 functions, the design of new drugs, and the development of new biotechnologies.
