Web2 dec. 2005 · First, ion-channel proteins, whose business is typically to catalyze the selective passage of ions at a high rate, have wide regions of their pores that allow ions to remain solvated by water as long as possible before reaching constrictions that confer selectivity; these regions are elements of protein structure that may span only a fraction ... WebMarine neurotoxins are natural products produced by phytoplankton and select species of invertebrates and fish. These compounds interact with voltage-gated sodium, potassium and calcium channels and modulate the flux of these ions into various cell types. This review provides a summary of marine neurotoxins, including their structures, molecular targets …
Web8 mrt. 2000 · Structure-function studies have shown that it is possible to convert a sodium channel to a calcium-selective channel by a single amino acid substitution in the selectivity filter locus. Ion permeation through the “model selectivity filter” was modeled with a reduced set of functional groups representative of the constituent amino acid side chains.
