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 ℃.
