Abstract
Hydrogen sulfide inhibits the inward-rectifying potassium ion current by inducing the persulfide modification on three cysteine residues of the inward potassium channel KAT1. This persulfidation inhibits the activity of KAT1 and KAT2 and suppresses the activity of heterologous channels formed by KAT1 and KAT2.
