AAK_AK-DapDC: Amino Acid Kinase Superfamily (AAK), AK-DapDC; this CD includes the N-terminal catalytic aspartokinase (AK) domain of the bifunctional enzyme AK - DAP decarboxylase (DapDC) found in some bacteria. Aspartokinase is the first enzyme in the aspartate metabolic pathway, catalyzes the conversion of aspartate and ATP to aspartylphosphate and ADP. DapDC, which is the lysA gene product, catalyzes the decarboxylation of DAP to lysine.
