Glutamate metabolism

Proteins involved in glutamate metabolism

Transport systems

• Ammonium uptake: AmtB, GlnK
• Glutamine uptake GlnQ-(GlnM-GlnP)-GlnH
• Glutamine uptake GlnT
• Glutamate uptake: GltT

Metabolic enzymes

• Glutamine synthetase: GlnA
• Glutamate synthase: GltA, GltB
• Glutamate dehydrogenases: GudB, RocG

Regulators

• Key regulators of nitrogen metabolism: GlnR, GltC, TnrA
• Additional regulators: AhrC, RocR, CcpA, Fur
