WebBK inhibition by PAX is best charac- terized by the idea that PAX gains access to the channel through the central cavity of the BK channel, and that only a single PAX molecule can interact with the BK channel at a time. The notion that PAX reaches its binding site via the central cavity and involves only a WebMay 29, 2007 · The inhibition efficiencies of the plant's part extracts follow the trend: LV > SD > HW > BK. Inhibition efficiency increased with extracts concentration but decreased with temperature. Physical adsorption of the phytochemical components of the plant on the metal surface is proposed as the mechanism of inhibition.
