• Curated by eLife

  Evaluation Summary:

  This study presents an in-depth analyses of carbon oxidation state and hydration state of proteomes in different taxa and environmental settings, which contributes to our understanding of how microbial communities are shaped by their surroundings. The study has merit, but there also some technical weaknesses.

  Evaluation Summary:

  Park et al.'s work provides insight into the infection processes of the human pathogen Coxiella burnetii with unprecedented detail. Their time course of cellular infection reveals the timing of key events and detects a previously unrecognized membrane structure. This work will shed new insight into the infection process of this pathogen allowing new targets for the treatment of infection with Coxiella.

  Evaluation Summary:

  This manuscript tackles the important question of what proteins regulate asymmetrical cell division in Mycobacteria. This will be of interest to all individuals interested in bacterial physiology. The data are sound, but some of the conclusions need to be tempered or bolstered, in relation to the models proposed.

• Curated by eLife

  Evaluation Summary:

  This paper will be of broad interest to those working on the regulation of gene expression and mycobacteria as it deals with the collaboration of two important transcription regulators. A combination of experiments indicates how a complex of two regulators selectively turns on gene expression of a few genes in intracellular pathogen Mycobacterium tuberculosis.

Temporal and thermal profiling of the Toxoplasma proteome implicates parasite Protein Phosphatase 1 in the regulation of Ca2+-responsive pathways

• Curated by eLife

  Evaluation Summary:

  Herneisen et al provide a comprehensive and thorough exploration of Ca2+ responsive changes in the Toxoplasma proteome and the resulting phosphorylation events during the transition from intracellular residing parasites to egress from the host cell. Furthermore, a novel temperature stability profiling method of all proteins responding to Ca2+ concentration with a change in stability is a novel applicable tool that here is used to map Ca2+-responsive proteins in the parasites. They provide a compelling analysis of the complex data and carefully validate their findings using genetics and cell biology. This work is of the highest quality in the field.

  Evaluation Summary:

  Trichomonas vaginalis is a sexually transmitted protist that colonizes its host by transitioning from flagellar locomotion to an adherent ameboid movement. In this manuscript, Wang and coauthors use a wide range of experimental approaches to investigate the function of a novel actin capping protein in T. vaginalis cytoadherence and cell motility. The work provides an intriguing example of how an unusual capping protein may impact cytoskeletal organization and cell behavior.
