研究结论

Date Results Publications
2017-12-02 10:40:00 Thermodynamic analysis of ion and proton binding shows how the structure of the CLC transporter effects the pH-independent, 2 Cl- to 1 proton binding stoichiometry. The key features are a helix cage, which creates a compact region with a very strong electropositive potential that stabilizes two anions and a single Glutamate that competes with two Cl ions. 28877486
2010-01-21 00:00:00 E203 substitution with Cys and crystal structures of mutants showed that respective Glu is the internal proton-transfer residue that delivers protons from intracellular solution to the protein interior 19139174
2010-01-21 00:00:00 The unitary Cl(-) transport rate, measured in liposomes by both initial-velocity method and a novel Poisson dilution approach, is approximately 4,000 s(-1) for wild-type protein, and the uncoupled mutants transport Cl(-) at similar rates 17389248
2010-01-21 00:00:00 The authors propose that CLC-ec1 operates through an affinity-switch mechanism and that the bases of substrate specificity are conserved in the CLC channels and transporters. 19898476
2010-01-21 00:00:00 Crystallographic study on the ion-binding properties of the ClC selectivity filter in the close homolog from Escherichia coli was presented. 16341087
