Mutational analysis of functional domains within plant K+ uptake channels.
Site-directed mutations have been generated in the pore and voltage sensor regions of the inwardly rectifying potassium channels KAT1 and KST1. The properties of mutant channels have been analysed in Xenopus oocytes, and give insights into the structure-function relations of these channels.
