Exploring Unspecific Peroxygenase Selectivity with Diverse Hydrocarbon Substrates
ChemistryOpen, EarlyView.Unspecific peroxygenases (UPOs) are versatile enzymes that can be used for different reactions. However, selectivity of UPOs needs to be evaluated for the desired application. Thus, the selectivity of a panel of UPOs was evaluated in this work, and it revealed diverse reactivity profiles depending on the enzyme and substrate.
