    Energy supply of heme import in bacteria : Cryo-EM structures of two membrane complexes

    Résumé : Gram negative bacteria import iron from their host cells via a two-membrane spanning complex energised by a TonB-like complex in the inner membrane. We solved the structures of two partners of TonB from Serratia marcescens: ExbB pentamer and its complex with ExbD. The structures show the detailed location of the partners and exhibit differences with respect to the E. coli complex.
