ABSTRACT
Almost all of the macromolecules in a bacterial cell, e.g., proteins, nucleic acids, and cell wall components, contain nitrogen. Thus, most prokaryotes have developed elaborate mechanisms to provide an optimal nitrogen supply for metabolism and to overcome and survive situations of nitrogen starvation. The uptake and assimilation of nitrogen sources in Corynebacterium glutamicum, as well as connected regulatory mechanisms, will be described in the following sections (for review, see also [5,6]).
