Mutations at position 334 disrupt ATP inhibition of Kir6.2ΔC26 channels. Response to indicated concentration of ATP of channels representative of strong and moderate disruption of ATP sensitivity is shown. NPO was determined at the different concentrations of ATP including 0 ATP. The strongest effects were obtained for the negative-charged aspartate and glutamate. The weakest effects were observed with the positive-charged arginine and lysine.
