1.12.2.1	synthesis	adsorption of cytochrome c3 at a pyrolytic graphite electrode is observed in the room-temperature ionic liquids 1-butyl-3-methylimidazolium tetrafluoroborate, 1-ethyl-3-methylimidazolium tetrafluoroborate and 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide. The electrochemical signal differs however from that obtained in aqueous buffer, and depended on the type of room-temperature ionic liquids. 1-Ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, as a hydrophobic non-water-miscible room-temperature ionic liquids, stabilizes the native form of cytochrome c3 and allows an amount of electroactive protein 30fold higher than observed in aqueous buffer. Catalytic oxidation of H2 via [NiFe] hydrogenase mediated by cytochrome c33 fails however, possibly due to inhibition of the hydrogenase in presence of room-temperature ionic liquids	-, 724835
