abstract = {Pdr5, a member of the extensive ABC transporter
superfamily, is representative of a clinically relevant
subgroup involved in pleiotropic drug resistance. Pdr5 and
its homologues drive drug efflux through uncoupled
hydrolysis of nucleotides, enabling organisms such as
baker’s yeast and pathogenic fungi to survive in the
presence of chemically diverse antifungal agents. Here, we
present the molecular structure of Pdr5 solved with single
particle cryo-EM, revealing details of an ATP-driven
conformational cycle, which mechanically drives drug
translocation through an amphipathic channel, and a clamping
switch within a conserved linker loop that acts as a
nucleotide sensor. One half of the transporter remains
nearly invariant throughout the cycle, while its partner
undergoes changes that are transmitted across inter-domain
interfaces to support a peristaltic motion of the pumped
molecule. The efflux model proposed here rationalises the
pleiotropic impact of Pdr5 and opens new avenues for the
development of effective antifungal compounds.},
