DOPA decarboxylase (DDC, aromatic L-amino acid decarboxylase, tryptophan decarboxylase, 5-hydroxytryptophan decarboxylase, AAAD) is an approximately 52 kDa protein that belongs to the aspartate aminotransferase family (fold type 1) of PLP-dependent enzymes. The catalytically active form exists as a homodimer, typical of this class of enzymes. It is responsible for the synthesis of dopamine and serotonin from L-DOPA and L-5- hydroxytryptophan, respectively. Due to its role in neurotransmitter synthesis, DOPA decarboxylase has been implicated in Parkinson's Disease. Currently, the design of more specific inhibitors is a major objective in Parkinson's Disease research.
