Aromatic L-amino acid decarboxylase is active as a homodimer. Before addition of the pyridoxal phosphate cofactor, the apoenzyme exists in an open conformation. Upon cofactor binding, a large structural transformation occurs as the subunits pull closer and close the active site. This conformational change results in the active, closed ...
l-DOPA is produced from the amino acid l-tyrosine by the enzyme tyrosine hydroxylase. l-DOPA can act as an l-tyrosine mimetic and be incorporated into proteins by mammalian cells in place of l-tyrosine, generating protease-resistant and aggregate-prone proteins in vitro and may contribute to neurotoxicity with chronic l-DOPA administration.

Aromatic L-amino acid decarboxylase deficiency has an autosomal recessive pattern of inheritance. Aromatic L-amino acid decarboxylase deficiency is an autosomal recessive condition, meaning an individual needs to have two faulty copies of the DDC gene in order to be affected. Usually, one copy is inherited from each parent. [3]
Tyrosine hydroxylase or tyrosine 3-monooxygenase is the enzyme responsible for catalyzing the conversion of the amino acid L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA). [5] [6] It does so using molecular oxygen (O 2), as well as iron (Fe 2+) and tetrahydrobiopterin as cofactors.
An aromatic L-amino acid decarboxylase inhibitor (synonyms: DOPA decarboxylase inhibitor, extracerebral decarboxylase inhibitor, DDCI and AAADI) is a medication of type enzyme inhibitor which inhibits the synthesis of dopamine by the enzyme aromatic L-amino acid decarboxylase (AADC, AAAD, or DOPA decarboxylase).
Eladocagene exuparvovec is indicated for the treatment of aromatic L-amino acid decarboxylase (AADC) deficiency. [3]Aromatic L-amino acid decarboxylase deficiency is a rare genetic disorder that affects the production of some neurotransmitters, which are chemical messengers that allow cells in the body's nervous system to communicate with each other.

Before iron deficiency anemia sets in, “the body will do everything it can to retain the right number of red blood cells. So, it will deplete the storage iron before it depletes the red blood ...
One of the L-DOPA's metabolic pathways is the decarboxylation and the other is the O-methylation. L-DOPA has the main role in the metabolic pathway as a metabolite in the biosynthesis of dopamine. This reaction happen in the process of decarboxylation by aromatic amino acid decarboxylase (AADC) also called dopa-descarboxilasa.
