    Mapping the functional landscape of the receptor binding domain of T7 bacteriophage by deep mutational scanning

    Phil Huss et al.
    An unbiased mutational screen decodes the molecular basis of phage receptor interactions, identifies key functional regions determining activity and host range, and demonstrates the potential for engineering therapeutic phages.

    HPF1 and nucleosomes mediate a dramatic switch in activity of PARP1 from polymerase to hydrolase

    Johannes Rudolph et al.
    The polymerase activity of PARP1 is converted to hydrolase activity upon binding of Histone Parylation Factor 1 (HPF1) with nucleosome activators.

    Disease-related mutations in PI3Kγ disrupt regulatory C-terminal dynamics and reveal a path to selective inhibitors

    Manoj K Rathinaswamy et al.
    The c-terminus of PI3K plays a key role in regulating kinase activity, with c-terminal disease-linked mutations leading to either activation or inhibition, which reveal a path to specific inhibitors.

    Evolutionary transcriptomics implicates HAND2 in the origins of implantation and regulation of gestation length

    Mirna Marinić et al.
    The transcription factor HAND2 evolved uterine expression during the origins of pregnancy and may be important for maternal-fetal immune signaling and parturition.

    Real-time monitoring of peptidoglycan synthesis by membrane-reconstituted penicillin-binding proteins

    Víctor M Hernández-Rocamora et al.
    The synthesis of bacterial cell wall peptidoglycan was reconstituted in lipid bilayers and detected by a novel Förster resonance energy transfer real-time assay.

    Redox controls RecA protein activity via reversible oxidation of its methionine residues

    Camille Henry et al.
    RecA is inactivated by oxidative stress and repaired by the MsrA/B anti-ROS defense system.

    Three-dimensional biofilm colony growth supports a mutualism involving matrix and nutrient sharing

    Heidi A Arjes et al.
    Novel high-throughput co-culture assays reveal how the spatial structure of colony biofilms provides opportunities for nutrient and matrix sharing and may drive the evolution of cooperative behaviors.

    Human primed ILCPs support endothelial activation through NF-κB signaling

    Giulia Vanoni et al.
    Circulating human primed innate lymphoid cell precursors have the potential to functionally induce adhesion molecules' expression in endothelial cells and possibly support the immune cells' infiltration into the tumor site.
