Abstract
The physiological role of the membrane-bound pyrophosphatase of Rhodospirillum rubrum was investigated by the characterization of a mutant strain. Comparisons of growth levels between the wild type and the mutant under different low-potential conditions and during transitions between different metabolisms indicate that this enzyme provides R. rubrum with an alternative energy source that is important for growth in low-energy states.Keywords
