    Structural model for differential cap maturation at growing microtubule ends

    Juan Estévez-Gallego, Fernando Josa-Prado ... Maria A Oliva
    The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.

    Inferring joint sequence-structural determinants of protein functional specificity

    Andrew F Neuwald, L Aravind, Stephen F Altschul
    A statistical approach for predicting non-active site residues responsible for allostery, cooperativity, or other subtle but functionally important interactions is described and applied to various protein families.

    Concurrent remodelling of nucleolar 60S subunit precursors by the Rea1 ATPase and Spb4 RNA helicase

    Valentin Mitterer, Matthias Thoms ... Roland Beckmann
    The RNA helicase Spb4 restructures rRNA helices H62/H63 and primes pre-ribosomal 60S intermediates for large-scale remodelling by the AAA-ATPase Rea1.

    Cryo-EM structures reveal high-resolution mechanism of a DNA polymerase sliding clamp loader

    Christl Gaubitz, Xingchen Liu ... Brian A Kelch
    Cryo-EM structures of the eukaryotic clamp loader illustrate the large conformational changes that the clamp loader ATPase undergoes to open the circular sliding clamp and place it onto primer–template DNA.

    Moyamoya disease factor RNF213 is a giant E3 ligase with a dynein-like core and a distinct ubiquitin-transfer mechanism

    Juraj Ahel, Anita Lehner ... Tim Clausen
    RNF213 is a giant E3 ligase with a dynein-like core and a unique ubiquitination mechanism that proceeds in a RING-independent manner and is linked with the Moyamoya disease.

    The yeast H+-ATPase Pma1 promotes Rag/Gtr-dependent TORC1 activation in response to H+-coupled nutrient uptake

    Elie Saliba, Minoas Evangelinos ... Bruno André
    The H+ influx coupled to nutrient uptake and the plasma membrane H+-ATPase are central actors of the activation of target of rapamycin complex 1 (TORC1) in budding yeast Saccharomyces cerevisiae..
