    Deconvoluting heme biosynthesis to target blood-stage malaria parasites

    Paul A Sigala et al.
    Insights into the basic metabolic architecture and adaptations of malaria parasites for growth within human erythrocytes exemplify how incisive knowledge of biochemical pathways and mechanisms may be leveraged to develop new therapies.

    The GluTR-binding protein is the heme-binding factor for feedback control of glutamyl-tRNA reductase

    Andreas S Richter et al.
    Heme-dependent feedback inhibition of rate-limiting ALA-synthesis of plant tetrapyrrole biosynthesis depends on binding of heme to glutamyl-tRNA reductase-binding protein.

    Systematic bacterialization of yeast genes identifies a near-universally swappable pathway

    Aashiq H Kachroo et al.
    Despite billions of years of divergence, a majority of prokaryotic genes can functionally replace their essential eukaryotic counterparts, revealing broad preservation of ancestral functions and identifying heme biosynthesis as a near-universally swappable pathway.

    Erythropoietin signaling regulates heme biosynthesis

    Jacky Chung et al.
    EPO/JAK2/PKA signaling cascade via AKAP10 relocalization to the outer mitochondrial membrane results in the phosphorylation of the terminal heme synthesis enzyme ferrochelatase, which contributes to heme production in red cells.

    Point of View: How should the applications of genome editing be assessed and regulated?

    Robin Fears, Volker ter Meulen
    An EASAC working group on genome editing recommends that regulators should focus on specific applications of these new techniques rather than attempting to regulate genome editing itself as a new technology.

    Principles of cellular resource allocation revealed by condition-dependent proteome profiling

    Eyal Metzl-Raz et al.
    Steadily growing cells prepare for conditions that demand increased translation by producing excess ribosomes, at the expense of lower steady-state growth rate.

    An orphan cbb3-type cytochrome oxidase subunit supports Pseudomonas aeruginosa biofilm growth and virulence

    Jeanyoung Jo et al.
    During growth in biofilms and host infection, the opportunistic pathogen Pseudomonas aeruginosa employs respiratory heterocomplexes that support extracellular electron shuttling and pathogenicity.

    Temporal profiling of redox-dependent heterogeneity in single cells

    Meytal Radzinski et al.
    Analysis of aging yeast cells using the in-vivo roGFP2-based probe reveals redox-dependent heterogeneity, reflected in a bi-modal distribution of the oxidation status, differential growth and replication, as well as distinct proteomic and transcriptomic profiles.
