    Structural basis of phosphatidylcholine recognition by the C2–domain of cytosolic phospholipase A2α

    Yoshinori Hirano, Yong-Guang Gao ... Rhoderick E Brown
    The C2-domain of cytoplasmic phospholipase A2α is structurally designed to target PC-rich membrane regions to increase the enzymatic efficiency of the catalytic domain, which prefers PCs with polyunsaturated acyl chains.

    Essential metabolism for a minimal cell

    Marian Breuer, Tyler M Earnest ... Zaida Luthey-Schulten
    A near-complete flux balance analysis model of a minimal cell demonstrates the high essentiality of its metabolic genes, agrees well with experimental essentiality data and suggests some further gene removals.

    A pH-dependent cluster of charges in a conserved cryptic pocket on flaviviral envelopes

    Lorena Zuzic, Jan K Marzinek ... Peter J Bond
    Benzene mapping simulations of envelope protein rafts from six different flaviviruses reveal a conserved cryptic site whose cluster of ionisable residues is likely responsible for orchestrating pH-dependent conformational changes during fusion, thereby representing an attractive target for antiviral development.

    A binding site for phosphoinositides described by multiscale simulations explains their modulation of voltage-gated sodium channels

    Yiechang Lin, Elaine Tao ... Ben Corry
    Simulations reveal where phosphoinositide lipids bind to voltage-gated sodium channels and how they reduce channel activity.
