The patch clamp technique using enlarged yeast tonoplasts is an effective approach to characterizing the Nicotiana tabacum plant tonoplast K+ channel, NtTPK1. We report here that the NtTPK1-mediated currents comprise two phase components, both which were found to be highly selective for K+ over Na+ and Cl-.
