    Interplay of disordered and ordered regions of a human small heat shock protein yields an ensemble of ‘quasi-ordered’ states

    Amanda F Clouser et al.
    Multiple iso-energetic-specific interactions involving the intrinsically-disordered region of sHSP HSPB1 define a quasi-ordered state, providing insights into inherited disease-associated mutations within the region that are thought to be disordered.

    Mitochondrial ClpX activates an essential biosynthetic enzyme through partial unfolding

    Julia R Kardon et al.
    The mitochondrial protein unfoldase ClpX activates the first enzyme in heme biosynthesis, ALAS, by targeted unfolding that gates access of cofactor to the ALAS active site.

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

    Yoshinori Hirano et al.
    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.

    Molecular basis for catabolism of the abundant metabolite trans-4-hydroxy-L-proline by a microbial glycyl radical enzyme

    Lindsey RF Backman et al.
    The common post-translational modification trans-4-hydroxy-L-proline is reversed by gut microbes with the help of hydroxyproline dehydratase (HypD), an enzyme that performs a radical chemical mechanism.
