  Evaluation Summary:

  This paper will be of interest to the lipid metabolism and transporter communities. Fatty acids that are too long to be transported into mitochondria are instead transported into peroxisomes for their break down i.e., beta-oxidation. The authors have determined the cryo-EM structure of human ABC transporter ABCD1 (ALDP), which translocates very-long-chain fatty acids (VLCFA) conjugated to coenzyme A across peroxisomal membranes, in complex with its substrate. While the work is well done, it is unclear what new mechanistic insights are gained from the ALDP structure. Also, the proposed conformational differences based on AlphaFold models should be taken with caution.

• Curated by eLife

  Evaluation summary

  This manuscript is of broad interest to the DNA-repair and structural biology field. The paper describes new insights into the interaction between ATM and Nsb1, proteins central to repairing DNA double-strand breaks in humans. Overall, the structural cryo-electron microscopy data is solid and the data well analyzed and presented with key claims directly related to and supporting previous known findings.

Systematic investigation of the link between enzyme catalysis and cold adaptation

  Evaluation Summary:

  Are enzymes found in organisms that optimally grow at colder temperatures are more active than the same enzymes found in organisms that optimally grow at warmer temperatures? Here, an assessment of the catalytic constants for approximately 2200 enzymes (obtained from the BRENDA database) showed no correlation between the relative catalytic activity and the optimum growth temperature. Further support for this conclusion was obtained from the measurement of the catalytic constant from a selection of ketosteroid isomerases from organisms that optimally grow between 15 and 46 degrees centigrade. These are interesting results, although the significance with respect to earlier studies has not been clearly explained.

• Curated by eLife

  Evaluation Summary:

  This manuscript describes the regulation of ERK1/2, two protein kinases that play important roles in cell signaling, by protein cysteine palmitoylation. The intriguing observations reported here could be of broad interest to colleagues in the field of cell signaling and protein post-translational modifications. Mechanistic understanding is, however, still limited and the work would benefit from additional experimental evidence.
