Structural basis of K+/H+ antiport in YcgO and its inhibition by unphosphorylated PtsN
Cation-proton antiporters (CPAs) are vital for the maintenance of ionic homeostasis and normal physiology among diverse cell types. Despite recent insights into K+/H+ exchange transporters, the diversity in their structural organization and regulatory mechanisms of K+-specific CPAs are minimally understood. Here, we ex...
