  Evaluation Summary:

  This paper is of potential interest to an audience of biochemists, cell biologists, and structural biologists working in the area of chromosome organization and segregation. A wide range of in vitro methods is used to provide compelling biochemical evidence for the interaction of MatP and ParEC at the hinge of MukB, the condensin of Enterobacteria. However, the evidence supporting the significance of these interactions in vivo is less strong, limiting the biological implications of the elegant biochemical findings.

• Curated by eLife

  Evaluation Summary:

  The authors report continuum electrostatics, molecular dynamics and QM/MM simulations to probe the protonation pattern of key residues in anion channelrhodopsin (GtACR1). The findings provide new mechanistic insights into the gating mechanism of GtACR1, and the study will be of potential interest for the community focused on biophysical chemistry, protein simulations and optogenetics. More generally, the study helps highlight that due to potential compensatory effects, care needs to be exercised when interpreting absorption spectra of mutant proteins.

• Curated by eLife

  Evaluation Summary:

  The manuscript by Yanofsky et al. describes the high-resolution structure of the CIII/CIV super-complex from Mycobacterium smegmatis bound to the anti-tuberculosis drug Q203 which is currently in clinical trials. The authors also provide biochemical data for inhibition of purified CIII/CIV and add important new information regarding the mechanism of Q203. This is an important contribution that will be of broad interest to the field of bioenergetic and tuberculosis, as telacebec represents one of few novel drug classes with potential for treatment of tuberculosis and other mycobacterial infections.
