Channel protein A hollow or pore-containing protein that spans a cell membrane and acts as a conduit for small molecules, such as charged particles (ions).
Channel proteins that span the cell membrane form the ion channels. To determine the structure of proteins, scientists have often used X-ray crystallography.
Channel proteins - form hydrophilic pores that extend across the lipid bilayer; when these pores open, they allow specific molecules to pass through them ...
Neurotransmitters are ligands that are capable of binding to ion channel proteins resulting in their opening to allow the rapid flow of a particular ion across the plasma membrane.
Channel proteins called porins in the outer membrane allow free movement of ions and small molecules into the intermembrane space.
Internal ligands bind to a site on the channel protein exposed to the cytosol.
Examples: ...
Ligand-gated channel A transmembrane channel that is opened by the binding of a one or more molecules to a ligand-binding domain of the channel protein.
Ligation reactions Reactions that form bonds by using the energy of ATP hydrolysis.
