应用

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

生化/生理作用

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.

其他说明

Dried cells grown on vitamin B6-deficient medium.

单位定义

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

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.
