Dopa Decarboxylase L-Aromatic Amino Acid

In the presence of the cofactor pyridoxyl phosphate, Dopa decarboxylase catalyzes the decarboxylation of L-dopa to dopamine. This enzyme has been shown to be the same protein as 5-hydroxytryptophan decarboxylase, and both are referred to by the name aromatic L-amino acid decarboxylase (AADC). 

SURVEY OF ENZYMATIC ACTIVITIES ASSAYED BY THE HPLC METHOD 

Samples were obtained from rat cerebral cortex. They were homogenized, and samples of the homogenate were used directly as the source of the activity.
