Abstract:

Heme peroxygenases exhibit remarkable catalytic versatility in facilitating a wide array of oxidative reactions under mild conditions, eliminating the need for coenzymes and intricate electron transport systems. This unique character underscores their essentiality and potential as promising tools in synthetic biology. Recent advancements in enzyme engineering have significantly enhanced the catalytic performance of both natural and artificial peroxygenases. Extensive engineering efforts have been directed towards unspecific peroxygenases and fatty acid peroxygenases, aiming to expand their substrate specificities, and enhance reaction selectivities, as well as increase enzyme stability. Furthermore, innovative strategies such as dual-functional small molecule-assisted systems and H2O2 tunnel engineering have been harnessed to transform P450 monooxygenases into highly efficient peroxygenases, capable of catalyzing reactions with a variety of unnatural substrates. This review consolidates the latest progress in the engineered and artificial heme peroxygenases, emphasizing their catalytic performances as potent biocatalysts for sustainable organic synthesis.
