Why does Escherichia coli have two primary pathways for synthesis of glutamate?

Journal of bacteriology - 1 Aug 1994

Helling R B

Abstract excerpt

Escherichia coli has two primary pathways for glutamate synthetase-glutamate synthase pathway is known to be essential for synthesis at low ammonium concentrations and for regulation of the glutamine pool, but the necessity for glutamate dehydrogenase (GDH) has been uncertain. The results of competition experiments between the wild type and a GDH-deficient mutant during nutrient-limited growth and of direct...
