dopa decarboxylase 95-OH tryptophan decarboxylase; aromatic L-amino-acid decarboxylase (DDC, AADC)

Function: - catalyzes decarboxylation of L-3,4-dihydroxyphenylalanine (DOPA) to dopamine L-5-hydroxytryptophan to serotonin L-tryptophan to tryptamine - catecholamine biosynthesis Cofactor: pyridoxal phosphate Structure: - homodimer - belongs to the group II decarboxylase family Pathology: - defects in DDC are the cause of aromatic-L-amino-acid decarboxylase deficiency Pharmacology: - AADC gene therapy investigational treatment of Parkinson's disease Laboratory: - L-dopa decarboxylase in plasma - L-dopa decarboxylase in CSF
