      Evaluation Summary:

      The authors analyze the mechanisms of entropically driven cooperativity in the human thymidylate synthase (hTS), an enzyme essential for DNA replication and a promising target for anticancer drugs. The authors conclude that the cooperative binding of dUMP ligands to its two identical sites arises from a disproportionate reduction in the enzyme's conformational entropy upon binding the first ligand. The results provide rare insights into the mechanisms of ligand binding for an essential human protein and should be of great interest to readers interested in enzyme structure/dynamics/function relationships, cooperativity and allostery, and possible drug targeting of thymidylate synthase.

  3. Structures of topoisomerase V in complex with DNA reveal unusual DNA-binding mode and novel relaxation mechanism

      Evaluation Summary:

      Osterman and Modragon report the first crystal structure of topoisomerase V in complex with DNA. Topoisomerase V is an unusual protein in that homologs have only been found in the archaeal Methanopyrus genus. The paper is likely of interest to those studying topoisomerase biology and biochemistry, and the wider audience interested in DNA replication and repair transactions.

  5. Evolutionary divergence of anaphase spindle mechanics in nematode embryos constrained by antagonistic pulling and viscous forces

      Evaluation Summary:

      This work will be of interest to cell biologists studying the mechanism of asymmetric cell division and its diversity across species. Building on their earlier work, the authors show that that there is considerable variability in the mechanics of the spindle among six nematode species studied here. While the authors' main conclusion is plausible - that spindle oscillations require high force and low viscosity - stronger support by the data would be needed.

      Evaluation Summary:

      The authors advance our understanding of the molecular underpinnings of allostery in GPCRs by showing the effects of allosteric modulators of mGluR2 on receptor conformation at distinct sites in the presence and absence of orthosteric modulators. This is important as drugs and drug candidates acting outside the site where the orthosteric or endogenous ligands bind are harder to identify. This work provides insights into allosteric changes at the level of individual receptors and provides a new path for drug discovery and is this of interest to colleagues studying GPCRs in health and disease.

      Evaluation Summary:

      This manuscript is of interest to several fields, in particular to microbiologists and structural biologists interested in pore-forming proteins and peptides. The data presented reveal insights into the mode of action of a newly identified peptide toxin secreted by Candida albicans (candidalysin). Using different techniques the authors propose and test a model for membrane perforation by candidalysin and identify an intriguing inactive mutant. While the presented data supports the main conclusions of the paper some of the initial assumptions need further assessment while the described mutants could benefit from more extensive characterization.

      Evaluation Summary:

      Hososhima et al. characterize a marine virus Heliorhodopsin as the first of its class to show ion transport activity. These bacteriorhodopsin homologs have been recently described and the present careful characterization of V2HeR3 represents an important step in the understanding of these interesting membrane proteins. Though the experiments are carried out carefully and the results, in general, support the conclusions, some experiments are needed and the interpretation of results needs to be clarified.
