P2X receptors are trimeric cation channels that open in response to the binding of adenosine triphosphate (ATP) to a large extracellular domain. The x-ray structure of the P2X4 receptor from zebrafish (zfP2X4) receptor reveals that the extracellular vestibule above the

Lactose permease of Escherichia coli (LacY) with a single-Cys residue in place of A122 (helix IV) transports galactopyranosides and is specifically inactivated by methanethiosulfonyl-galactopyranosides (MTS-gal), which behave as unique suicide substrates. In order to study the mechanism of inactivation more

Many clinically important drugs target ligand-gated ion channels; however, the mechanisms by which these drugs modulate channel function remain elusive. Benzodiazepines (BZDs), anesthetics, and barbiturates exert their CNS actions by binding to GABA(A) receptors and modulating their function. The structural
