说明

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

Biochem/physiol Actions

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.

Other Notes

Dried cells grown on vitamin B₆-deficient medium.

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