An Accessory Agonist Binding Site Promotes Activation of α4β2* Nicotinic Acetylcholine Receptors*
Background: In (α4β2)2α4 nicotinic acetylcholine receptors, there is an agonist binding site at the α4/α4 subunit interface. Results: α2, α3, and α6 accessory subunits can form an agonist site with α4.

Functional Stoichiometry at the Nicotinic Receptor. The Photon Cross Section for Phase 1 Corresponds to Two Bis-Q Molecules per Channel [PDF]
These experiments examine changes in the agonist-induced conductance that occur when the agonist-receptor complex is perturbed. Voltage-clamped Electrophorus electroplaques are exposed to the photoisomerizable agonist trans-Bis-Q A 1-µs laser flash ...

Molecular adsorption study of nicotine and caffeine on the single-walled carbon nanotube from first principles [PDF]
Using first-principles calculations, we investigate the electronic structures and binding properties of nicotine and caffeine adsorbed on single-walled carbon nanotubes to determine whether CNTs are appropriate for filtering or sensing nicotine and caffeine molecules. We find that caffeine adsorbs more strongly than nicotine.

Identification of critical residues in loop E in the 5-HT(3AS)R binding site [PDF]
BACKGROUND: The serotonin type 3 receptor (5-HT(3)R) is a member of a superfamily of ligand gated ion channels. All members of this family share a large degree of sequence homology and presumably significant structural similarity.

Single Molecule Transistor based Nanopore for the detection of Nicotine [PDF]
A nanopore based detection methodology was proposed and investigated for the detection of Nicotine. This technique uses a Single Molecular Transistor (SMT) working as a nanopore operational in the Coulomb Blockade regime. When the Nicotine molecule is pulled through the nanopore area surrounded by the Source(S), Drain(D) and Gate electrodes, the charge
