Abstract The main property of an Amt- (ammonium transport negative) mutant of Klebsiella pneumoniae is its inability to accumulate NH 4 + intracellularly. When growing on nitrogen sources other than NH 4 + , the mutant constantly looses NH3 by diffusion. This loss results in poor growth. The NH3 excretion suggests the existence of a futile cycle (NH3 loss/NH 4 + reabsorption) in the wild type and possibly other bacterial strains, which do not constantly excrete NH3.
