The invention relates to synthetic or isolated hydrogenases, to a method for the production thereof, host cells, in particular algal cells or cyanobacterial cells, said cells being transformed by DNA coding for the claimed hydrogenases and the use of hydrogenases and host cells. The aim of the invention is to provide the possibility to produce hydrogen via biological paths, in particular under aerobic conditions. The invention also aims provide the possibility to directly convert light energy into hydrogen via biological paths. As a result, the invention also relates to a synthetic hydrogenase which is derived from a protein comprising an H-donor cofactor binding point, and comprises, in the region of the NADHH donor cofactor binding point, a proton releasing amino acid radical which is not present in the protein. |
