Application

L-Tyrosine decarboxylase apoenzyme from Streptococcus faecalis has been used:
  • in a study to purify and characterize tyrosine decarboxylase and aromatic-L-amino-acid decarboxylase
  • in a study to investigate the stereospecificity of sodium borohydride reduction of tyrosine decarboxylase
  • in protein synthesis studies

Actions biochimiques/physiologiques

L-Tyrosine Decarboxylase Apoenzyme is an aromatic L-amino acid decarboxylase. The enzyme activity of tyrosine decarboxylase (TDC) is dependent on the cofactor pyridoxal 5-phosphate (PLP). It catalyzes the decarboxylation of dihydroxyphenylalanine.

Autres remarques

Dried cells grown on vitamin B6-deficient medium.

Définition de l'unité

One unit will liberate 1.0 μmole of CO2 from L-tyrosine per min at pH 5.5 at 37 °C.

Tyrosine decarboxylase (TDC) is a pyridoxal 5-phosphate (PLP)-dependent enzyme and is mainly responsible for the synthesis of tyramine, an important biogenic amine. In this study, the crystal structures of the apo and holo forms of Lactobacillus brevis TDC (LbTDC) were

Sodium boro[3H]hydride reduction of tyrosine decarboxylase from Streptococcus faecalis followed by complete hydrolysis of the enzyme produces epsilon-[3H]pyridoxyllysine. Degradation of this material to [4'-3H]pyridoxamine and stereochemical analysis with apoaspartate aminotransferase shows that the re side at C-4' of the cofactor

Phenolic melanin precursors can be utilized for the development of anti-melanoma agents. The sulphur homologue of tyrosine, 4-S-cysteinylphenol (CP) and its decarboxylation product, 4-S-cysteaminylphenol (CAP) were shown to be substrates of melanoma tyrosinase, forming melanin-like pigment. Both, but in particular
