CC   -!- FUNCTION: Responsible for the low-affinity transport of potassium into
CC       the cell, with the probable concomitant uptake of protons (symport
CC       system). {ECO:0000255|HAMAP-Rule:MF_01522}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_01522}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_01522}.
CC   -!- SIMILARITY: Belongs to the HAK/KUP transporter (TC 2.A.72) family.
CC       {ECO:0000255|HAMAP-Rule:MF_01522}.
