    Tuning site-specific dynamics to drive allosteric activation in a pneumococcal zinc uptake regulator

    Daiana A Capdevila et al.
    Internal dynamics play a crucial functional role in MarR (multiple antibiotic resistance repressor) proteins and their role reconciles the distinct allosteric mechanisms proposed previously.

    Screening of candidate substrates and coupling ions of transporters by thermostability shift assays

    Homa Majd et al.
    It is technically difficult to identify transport proteins, but here a method is presented that exploits the principle that they are stabilized in detergent solution when they bind their substrate.

    Specific structural elements of the T-box riboswitch drive the two-step binding of the tRNA ligand

    Jiacheng Zhang et al.
    The glycine T-box riboswitch recognizes tRNAgly and senses its aminoacylation state by first interacting with the anticodon region and subsequently probing the 3' end of the ligand using both specific structural elements and conformational dynamics.

    Calcium-dependent electrostatic control of anion access to the pore of the calcium-activated chloride channel TMEM16A

    Andy KM Lam, Raimund Dutzler
    Ion conduction in the calcium-activated chloride channel TMEM16A is directly regulated by calcium, which binds to a site close to the pore thereby shaping the electrostatics at its intracellular entrance.
