A metabolic connection joins synthesis of an amino acid, lysine, to synthesis of cell wall material. Diaminopimelate is a precursor both for lysine and for cell wall components. The synthesis of lysine, methionine and threonine share two reactions at the start of the three pathways, the reactions converting L-aspartate to L-aspartate semialdehyde. The first reaction, aspartate kinase, is carried out by three isozymes, one specific for synthesis of each end product amino acid. Each of the three aspartate kinase isozymes is regulated by its corresponding end product amino acid.
