    Mechanistic insight into the conserved allosteric regulation of periplasmic proteolysis by the signaling molecule cyclic-di-GMP

    Debashree Chatterjee et al.
    Structure-function analyses reveal the mechanistic underpinnings of inside-out transmembrane signaling that controls periplasmic proteolysis, and thereby biofilm formation, in bacteria and may be relevant in the context of other signaling proteins with similar control elements.

    Structural basis for interdomain communication in SHIP2 providing high phosphatase activity

    Johanne Le Coq et al.
    The SHIP2 inositol phosphatase is an important upstream regulator of the Akt signaling pathway, which requires a catalytic core formed by the phosphatase domain tightly packed to a C2 domain for its function.
