Comments [?]

case <OC:Enterobacterales>
Function Responsible for the low-affinity transport of potassium into the cell. Likely operates as a K(+):H(+) symporter.
else
Function Transport of potassium into the cell. Likely operates as a K(+):H(+) symporter.
end case
Catalytic activity RHEA:28490: H(+)(in) + K(+)(in) = H(+)(out) + K(+)(out)
PhysiologicalDirection=right-to-left (RHEA:28492)
