Data show that in KAT-type K(+) channel KAT1, residue K85 within the linker forms a hydrogen bond with C211 that enables the pH activation.
Title: The S1-S2 linker determines the distinct pH sensitivity between ZmK2.1 and KAT1.

Plant stress metabolite acrolein inhibits light-induced stomatal opening through inhibition of KAT1 potassium channels in Arabidopsis thaliana.
Title: Inhibition by acrolein of light-induced stomatal opening through inhibition of inward-rectifying potassium channels in Arabidopsis thaliana.

Mutations of the central Phe residue favored the closed KAT1 channel, whereas mutations affecting the countercharge centers favored the open channel
Title: Voltage-sensor transitions of the inward-rectifying K+ channel KAT1 indicate a latching mechanism biased by hydration within the voltage sensor.

CPK13 reduces stomatal aperture through its inhibition of the guard cell-expressed KAT2 and KAT1 channels.
Title: CPK13, a noncanonical Ca2+-dependent protein kinase, specifically inhibits KAT2 and KAT1 shaker K+ channels and reduces stomatal opening.

instead of single key amino acids, several titratable residues contribute to the pH-sensor of the plant Kin channel KAT1
Title: The pH sensor of the plant K+-uptake channel KAT1 is built from a sensory cloud rather than from single key amino acids.
