  • Here the authors determined several cryo-EM structures of the human Elongator complex, which modifies anticodons of tRNAs. The structural work is complemented by functional analyses to understand this clinically relevant cellular machine at the molecular level.

  • Nucleotide excision repair is able to identify and remove a wide range of DNA helix distorting lesions from the genome. Here the authors use single molecule imaging of UvrA and UvrB molecules and suggest a two-step ‘scan and recruit’ model for UvrA function.

  • Nucleotide excision repair is one of the main pathways for removal of damaged DNA. UvrA, which finds the damaged DNA, has broad specificity. The first crystal structure of UvrA in complex with DNA shows that the UvrA dimer does not contact the lesion directly but instead probes the conformation of the DNA around the modified residue.

  • Cryo-EM structures of cytb6f with quinone bound in the Qn site allow the identification of specific proton channels and reveal differences to known inhibitors. Nearby water channels imply a ‘piston-like’ mechanism during catalytic turnover.
