Cryo-EM structures of engineered active bc 1-cbb 3 type CIII2CIV super-complexes and electronic communication between the complexes

Abstract

Respiratory chains generate the proton motive force used for ATP synthesis. Cryo-EM structures of functional respiratory CIII2CIV supercomplex and native CIII2 from Rhodobacter capsulatus provide insight into CIII2CIV assembly and respiratory electron transport pathways in Gram-negative bacteria.
