Abstract: Hybrid proteins with cytochrome P450 activity and which are encapsulated in a nanocapsid (nanoparticles charged with cytochrome P450 activity) are designed and synthesized, these hybrid proteins being immunologically inert and recognized by breast cancer cells.

Abstract: The invention relates to a method of removing thiophenic and organosulfide compounds from a fossil fuel comprising the steps of contacting the fossil fuel with hemoproteins, which oxidize the sulfur containing compounds to sulfoxides and sulfones in a reaction system containing organic solvent or not, and followed by a distillation step in which sulfoxides and sulfones are removed from the fuel. Preferred biocatalysts include hemoproteins such as chloroperoxidase from Caldariomyces fumago, and peroxidases and cytochromes from animal, plant or microbial cells. The hemoprotein biocatalyst can be contacted with the fossil fuel in free or immobilized forms. The reaction can be carried out in the presence of the fuel alone or with addition of any organic solvent. The biocatalytically oxidized fuel is then distilled in order to eliminate the heavy fraction which contains most of oxidized organosulfur compounds.
