Oxygenases catalyze, among other interesting reactions, highly selective hydrocarbon oxyfunctionalizations, which are important in industrial organic synthesis but difficult to achieve by chemical means. Many enzymatic oxygenations have been described, but few of these have been scaled up to industrial
