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.Keywords
