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 decarboxylasein a study to investigate the stereospecificity of sodium borohydride reduction of tyrosine decarboxylasein 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.
