Abstract

The genus is heterogeneous with respect to the presence of the ammonia assimilating enzymes glutamine synthetase (GS), NADP-linked glutamate synthase (GOGAT) and NADP-linked glutamate dehydrogenase. Three major groups were distinguished; one showed activity of all three enzymes, the second only GS and GOGAT activity and the third only GS activity. Aspartase did not appear to be significant in ammonia assimilation in any group.
