Reactions of DOPA (3,4-dihydroxyphenylalanine) decarboxylase with DOPA [PDF]
, 1979 The study of DOPA (3,4-dihydroxyphenylalanine) decarboxylase by steady-state methods is difficult because multiple reactions occur. The reaction with DOPA was studied at enzyme concentrations between 20 and 50 micrometer by direct observation of the ...

Reaction specificity of native and nicked 3,4-dihydroxyphenylalanine decarboxylase
, 1999 3,4-Dihydroxyphenylalanine (Dopa) decarboxylase is a stereospecific pyridoxal 5'-phosphate (PLP)-dependent α-decarboxylase that converts L- aromatic amino acids into their corresponding amines.

Study of 3,4-dihydroxyphenylalanine (DOPA) as anchoring unit to functionalize biomaterials [PDF]
, 2018 This project aims at studying and comparing the efficiency and stability of the binding of a model peptide to a diverse range of biomaterials using L-3,4-dihydroxyphenylalanine (DOPA) which contains catechol groups, as anchoring unit.

Melanin Polymerization Held in Check: A Composite of Dihydroxyphenylalanine with Zeolite Beta
, 2015 The potential use of l-3,4-dihydroxyphenylalanine (l-DOPA) amino acid in the treatment of Parkinson’s disease is hindered by an oxidative polymerization under air that might be at least partially circumvented by the immobilization on an inorganic matrix.

Evidence for PQQ as cofactor in 3,4-dihydroxyphenylalanine (dopa) decarboxylase of pig kidney [PDF]
, 1988 Pig kidney 3,4-dihydroxyphenylalanine (dopa) decarboxylase (EC 4.1.1.28) was purified to homogeneity. Treatment of the enzyme with phenylhydrazine (PH) according to a procedure developed for analysis of quinoproteins gave products which were identified ...
