Structure-based redesign of Fe(ii)/2-oxoglutarate-dependent oxygenase AndA to catalyze spiro-ring formation†
Abstract
Structure- and mechanism-based redesign of the Fe(II)/2-oxoglutarate-dependent oxygenase AndA was performed. The function of AndA was expanded to catalyze a spiro-ring formation reaction from an isomerization reaction. The redesigned AndA variants produced two unnatural novel spiro-ring containing compounds through two and three consecutive oxidation reactions.
