In molecular biology the amino acid kinase domain is a protein domain. It is found in protein kinases with various specificities including the aspartate glutamate and uridylate kinase families. In prokaryotes and plants the synthesis of the essential amino acids lysine and threonine is predominantly regulated by feed-back inhibition of aspartate kinase (AK) and dihydrodipicolinate synthase (DHPS).
