FIG. 1.

The split pathway of m-DAP synthesis for the formation of m-DAP and l-lysine as present in C. glutamicum. On the left is shown the succinylase variant, on the right the dehydrogenase variant. Some bacteria have only the succinylase or dehydrogenase variant. The third acetylase variant is comparable to the succinylase variant but uses acetyl groups instead of succinyl groups. SuccCoA, succinyl coenzyme A; CoA, coenzyme A.
