    Large-scale filament formation inhibits the activity of CTP synthetase

    Rachael M Barry et al.
    The accumulation of its product, cytidine triphosphate, encourages the enzyme CTP synthetase (CtpS) to form large-scale polymers and inhibits the enzyme's activity.

    Evolutionarily conserved long-chain Acyl-CoA synthetases regulate membrane composition and fluidity

    Mario Ruiz et al.
    Silencing the acyl-coA synthethase ACSL1 protects against saturated fat lipotoxicity by preventing the degradation of polyunsaturated fatty acids, allowing them to be incorporated into phospholipids and improves membrane fluidity.

    Cryo-EM reveals distinct conformations of E. coli ATP synthase on exposure to ATP

    Meghna Sobti et al.
    Cryo-EM studies reveal that incubation with ATP produces conformational intermediates of E. coli ATP synthase, in which the ε subunit is no longer in its autoinhibitory conformation.

    tRNA synthetase counteracts c-Myc to develop functional vasculature

    Yi Shi et al.
    In addition to its cytoplasmic role for translation, the seryl-tRNA synthetase also antagonizes the c-Myc transcription factor in the nucleus to transcriptionally repress the growth factor VEGFA and ensure proper development of the vasculature in vertebrates.

    Bacterial cell cycle control by citrate synthase independent of enzymatic activity

    Matthieu Bergé et al.
    A key enzyme of central energy metabolism, citrate synthase, regulates bacterial cell cycle progression at a very specific stage (S-phase) and independently of its enzymatic activity.

    Cryo-EM structures of the autoinhibited E. coli ATP synthase in three rotational states

    Meghna Sobti et al.
    A molecular model that provides a framework for interpreting the wealth of functional information obtained on the E. coli F-ATP synthase has been generated using cryo-electron microscopy.

    Structural basis of proton translocation and force generation in mitochondrial ATP synthase

    Niklas Klusch et al.
    Cryo-EM reveals atomic details of two membrane half-channels for translocation of protons that drive rotary catalysis in ATP synthase.

    Structure and conformational states of the bovine mitochondrial ATP synthase by cryo-EM

    Anna Zhou et al.
    Structural analysis of the ATP synthase – in combination with evolutionary covariance analysis – reveals the fold of the a subunit and shows that the enzyme can adopt several different conformations, which support the Brownian ratchet model for generating rotation.
