Abstract/OtherAbstract:
Nitrogen is one of the macronutrients necessary for living cells, and consequently, assimilation of nitrogen is a crucial step for metabolism. To satisfy their nitrogen demand and to ensure a sufficient nitrogen supply even in situations of nitrogen limitation, microorganisms have evolved sophisticated uptake and assimilation mechanisms for different nitrogen sources. This mini-review focuses on nitrogen metabolism and its control in the biotechnology workhorse Corynebacterium glutamicum, which is used for the industrial production of more than 2 million tons of L: -amino acids annually. Ammonium assimilation and connected control mechanisms on activity and transcription level are summarized, and the influence of mutations on amino acid pools and production is described with emphasis on L: -glutamate, L: -glutamine, and L: -lysine.
