High stability in organic solvent of heme proteins immobilized in the interlayers of magadiite nanoparticles

Enzymatic activities of heme proteins, myoglobin (Mb) and hemoglobin (Hb), immobilized in the interlayers of magadiite nanoparticles under mild condition, toward the oxidation of o-phenylenediamine (OPD) in an organic solvent were firstly reported. The immobilized heme proteins showed higher stability than that of free Mb and Hb in organic toluene solution.
