We are interested in the structural biology of large membrane protein complexes. We have solved by X-ray crystallography the first atomic structure of the bacterial complex I (~550 kDa, 16 subunits, 9 Fe-S clusters, 64 TM helices). We also solved by cryo-EM the first complete atomic structure of the more elaborate mammalian complex I (~ 1 MDa, 45 subunits, 78 TM helices), as well as determined the architecture of respiratory supercomplexes.
