    Myoglobin primary structure reveals multiple convergent transitions to semi-aquatic life in the world's smallest mammalian divers

    Kai He et al.
    Ancestral sequence reconstruction of an essential muscle protein involved in oxygen storage and transport accurately tracks secondary aquatic transitions in a speciose clade of insectivorous mammals.
    1. Evolutionary Biology

    Convergent changes in muscle metabolism depend on duration of high-altitude ancestry across Andean waterfowl

    Neal J Dawson et al.
    Changes in pathways of lipid oxidation, glycolysis, and mitochondrial oxidative phosphorylation are common strategies to cope with high-altitude hypoxia, but some changes require longer evolutionary time to arise.

    Enabling X-ray free electron laser crystallography for challenging biological systems from a limited number of crystals

    Monarin Uervirojnangkoorn et al.
    Post-refinement methods enable the use of X-ray free electron lasers for biological crystallography of systems in which sample quantity is a limitation.

    A Sec14-like phosphatidylinositol transfer protein paralog defines a novel class of heme-binding proteins

    Danish Khan et al.
    A new class of fungal hemoproteins is described that emphasizes the versatility of the Sec14-fold for translating binding of chemically distinct ligands to control of diverse sets of cellular activities.

    Acquisition of exogenous haem is essential for tick reproduction

    Jan Perner et al.
    The lack of haem biosynthetic and degradative pathways in ticks offers new strategies to combat these parasites.

    Regulation of nerve growth and patterning by cell surface protein disulphide isomerase

    Geoffrey MW Cook et al.
    The nerve growth-repellent activity that generates spinal nerve repeat-patterning in birds and mammals is identified at the molecular level, and a similar system is revealed in adult brain grey matter.

    Endothelial heterogeneity across distinct vascular beds during homeostasis and inflammation

    Ankit Jambusaria et al.
    Vascular endothelial cells in the brain, heart and lung exhibit tissue-specific heterogeneity and plasticity, expressing genes that were traditionally thought to be only expressed by the surrounding parenchymal tissue cells.

    Elucidation of the anti-autophagy mechanism of the Legionella effector RavZ using semisynthetic LC3 proteins

    Aimin Yang et al.
    Legionella effector RavZ evades host autophagy by extracting LC3-PE from the membrane before deconjugation.

    Molecular mechanism of activation-triggered subunit exchange in Ca2+/calmodulin-dependent protein kinase II

    Moitrayee Bhattacharyya et al.
    Closed-ring and open-spiral assembly of the multi-subunit neuronal kinase CaMKII suggest a mechanism for how active subunits shuttle between individual assemblies, propagating stimulatory signals.
