It was derepressed when either l-glutamate or nitrate was used as nitrogen source. Glutamate synthase was repressed by l-glutamate or l-arginine and, to a lesser extent, by l-glutamine but was derepressed during growth with ammonia or nitrate. Glutamine synthetase activity was unaltered during the onset of sporulation. Glutamate synthase activity, however, underwent a small and apparently transient increase in bacteria induced to sporulate by nitrogen limitation., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-112-2-373
