Molecular Mechanism of pH-Dependent Activation in Human Equilibrative Nucleoside Transporter 3.
Human equilibrative nucleoside transporter 3 (hENT3) is a lysosomal transporter whose activity is strictly dependent on an acidic lumenal environment. Mutations in hENT3 lead to H syndrome and other metabolic disorders, yet the structural basis for its pH-sensitive gating remains poorly defined. Using multi-replica con...
