    ATP binding drives substrate capture in an ECF transporter by a release-and-catch mechanism

    Bacterial energy-coupling factor (ECF) transporters mediate ATP-dependent uptake of essential environmental micronutrients. Biochemical and fluorescence analyses now show that ATP binding promotes release of a...

    Antidepressant specificity of serotonin transporter suggested by three LeuT–SSRI structures

    Sertraline (Zoloft) and fluoxetine (Prozac) are selective serotonin-reuptake inhibitors (SSRIs) that are widely prescribed to treat depression. They bind to the presynaptic plasma membrane serotonin transporte...
