title: Mutations in GltC that increase Bacillus subtilis gltA expression.
abstract: Mutants with altered forms of GltC, a positive LysR-type regulator of Bacillus subtilis glutamate synthase gene expression, were isolated. The mutant GltC proteins stimulated expression from the wild-type gltA promoter region 1.5- to 2.0-fold and from mutant promoter regions up to 80-fold. Moreover, expression of gltA became much less dependent on a nitrogen source-associated signal.
