## Abstract Ammonium uptake into the cell is known to be mediated by ammonium transport (Amt) proteins, which are present in all domains of life. The physiological role of Amt proteins remains elusive; indeed, loss‐of‐function experiments suggested that Amt proteins do not play an essential role in
