    Resistance to different anthracycline chemotherapeutics elicits distinct and actionable primary metabolic dependencies in breast cancer

    Shawn McGuirk, Yannick Audet-Delage ... Julie St-Pierre
    Breast cancer resistant to either doxorubicin or epirubicin relies on distinct primary metabolic processes, which can be targeted to reduce cancer progression.

    Large-scale filament formation inhibits the activity of CTP synthetase

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

    Molecular structure of human KATP in complex with ATP and ADP

    Kenneth Pak Kin Lee, Jue Chen, Roderick MacKinnon
    MgADP binding to the high-affinity 'consensus' ATPase active site of SUR1 and remodeling of the L0-loop (lasso region) overrides tonic ATP inhibition of KATP channels.

    A CTP-dependent gating mechanism enables ParB spreading on DNA

    Adam SB Jalal, Ngat T Tran ... Tung BK Le
    A structural and biochemical approach shows that CTP binding and hydrolysis regulate nucleation, spreading, and recycling of a chromosome segregation protein ParB.

    Released bacterial ATP shapes local and systemic inflammation during abdominal sepsis

    Daniel Spari, Annina Schmid ... Guido Beldi
    Bacteria release ATP as part of their attack in sepsis.

    Cooperation among c-subunits of FoF1-ATP synthase in rotation-coupled proton translocation

    Noriyo Mitome, Shintaroh Kubo ... Shoji Takada
    Biochemical analysis on hetero-mutated c10 subunits ring and molecular dynamics simulations demonstrate the cooperation among c-subunits of FoF1-ATP synthase in rotation-coupled proton translocation.

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

    Meghna Sobti, Callum Smits ... Alastair G Stewart
    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.

    Dual roles for ATP in the regulation of phase separated protein aggregates in Xenopus oocyte nucleoli

    Michael H Hayes, Elizabeth H Peuchen ... Daniel L Weeks
    The equilibrium between solubility and aggregation of proteins in the nucleus is controlled by co-aggregates like RNA and the action of ATP as both an energy source and a destabilizing chemical agent.

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

    Anna Zhou, Alexis Rohou ... John L Rubinstein
    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.

    Nucleotide binding to the ATP-cone in anaerobic ribonucleotide reductases allosterically regulates activity by modulating substrate binding

    Ornella Bimai, Ipsita Banerjee ... Derek T Logan
    The first structural and biochemical study of the role of the ATP-cone in anaerobic ribonucleotide reductases shows that dATP allosterically prevents transfer of a glycyl radical to the substrate.
