Methane monooxygenases (MMOs), found in methanotrophic bacteria, are selective catalysts for methane activation and conversion to methanol under mild conditions; however, these enzymes are not amenable to standard enzyme immobilization approaches. The enzymes retain up to 100% activity in the polymer construct.
