Figure 9.

Voltage- and [ATP]-dependent gating does not change depending on the location of one T339S relative to D315A in the trimer; trans (D315A–T339S–WT) and cis (WT–D315A&T339S–WT) showed similar voltage- and [ATP]-dependent gating. (A and B) Normalized voltage-induced activation traces of trans (A) and cis constructs (B) at various [ATP] from the representative traces shown in Fig. S11. (C and D) Dependence of the activation kinetics on voltage and [ATP] for trans (C) and cis (D) constructs. Mean (± SEM) activation time constants for trans (C; n = 12–16) and cis (D; n = 9–14) constructs at various [ATP] and membrane potentials are shown. (E and F) Mean (± SEM) normalized G-V relationships at various [ATP] for trans (C; n = 7–14) and cis (D; n = 6–10) constructs derived from the maximum tail current responses by fitting with the two-state Boltzmann equation, as described in Materials and methods. (G and H) Mean (± SEM) V1/2 (mV) (G) and Z (H) values for the trans (C; n = 7–14) and cis (D; n = 6–10) constructs.
