    Report
  • Bioactivity

    Measured by its ability to convert the substrate 3, 4­dihydroxy L­phenylalanine (L­Dopa) to 3, 4­dihydroxyphenylethylamine (dopamine). The dopamine product is measured by its absorbance at 340 nm after derivatization with trinitrobenzene sulfonic acid. The specific activity is >1000 pmol/min/µg (QC tested).

Background

Dopa decarboxilase (DDC), also known as aromatic amino acid decarboxylase, is a group II decarboxylase. The enzyme catalyzes the decarboxylation of aromatic L-amino acids to produce the corresponding amines. DDC produces the neurotransmitters dopamine and serotonin from L-Dopa and L-5-hydroxytryptophan, respectively. DDC inhibitors is in clinical use to treat Parkinson's disease(PD), usually co-administrated with L-DOPA. DDC would block peripheral conversion to dopamine and allow a greater percentage of L-DOPA to reach the brain, causing an increase in brain dopamine levels, and reducing the side effects of dopamine-rich blood.
