Biochem/physiol Actions

6-Hydroxy-DL-DOPA is an inhibitor of APE1 (apurinic/apyrimidinic endonuclease) repair-function activity. APE1 is a nuclease crucial for DNA base excision repair pathway. 6-Hydroxy-DL-DOPA also blocks RAD52 (DNA repair protein) single-stranded DNA binding domain.

Precursor of the catecholaminergic neurotoxin, 6-hydroxydopamine; converted to 6-hydroxydopamine by L-aromatic amino acid decarboxylase.

Packaging
