    Evolution of a functionally intact but antigenically distinct DENV fusion loop

    Rita M Meganck, Deanna Zhu ... Longping V Tse
    Operating as a serum profiling tool for dengue infection and vaccination, the D2-FLM variant, which is insensitive to antibody-dependent enhancement-prone fusion loop antibodies, also offers potential for a safer dengue virus vaccine.

    RNA sequence to structure analysis from comprehensive pairwise mutagenesis of multiple self-cleaving ribozymes

    Jessica M Roberts, James D Beck ... Eric J Hayden
    A high-throughput analysis of several self-cleaving ribozymes reveals the effect of every possible mutation, and every possible pair of mutations, and how patterns in the relative activity data can be mapped to canonical and non-canonical structural elements.

    Atomic mutagenesis in ion channels with engineered stoichiometry

    John D Lueck, Adam L Mackey ... Christopher A Ahern
    Building on previous work (Pless, 2013), we argue that side-chain 'flip out' is a key event in potassium channel C-type inactivation, and propose a new method for encoding multiple noncanonical amino acids and controlling protein stoichiometry.

    High-resolution mapping demonstrates inhibition of DNA excision repair by transcription factors

    Mingrui Duan, Smitha Sivapragasam ... Peng Mao
    Transcription factor proteins play an important role in modulating base damage formation and excision repair at the binding sites in the genome.

    Repair of naturally occurring mismatches can induce mutations in flanking DNA

    Jia Chen, Brendan F Miller, Anthony V Furano
    The repair of spontaneous DNA damage can introduce mutators that lead to further genetic changes, which could underlie evolutionary change, disease and aging.

    Deconstruction of the Ras switching cycle through saturation mutagenesis

    Pradeep Bandaru, Neel H Shah ... John Kuriyan
    Sequence conservation in Ras depends strongly on the biochemical network in which it operates, providing a framework for understanding the origin of global selection pressures on proteins.
