Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

Ever since the FDA approved the drug bedaquiline, which interferes with the bioenergetics of Mycobacterium tuberculosis by inhibiting the activity the F0F1-ATP synthase, respiratory-chain enzymes have been an active target space for the discovery of new antibiotics. To aid in this pursuit, we aim to…
