Application【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
Biochem/physiol Actions【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.
Other Notes【其他说明】
Dried cells grown on vitamin B6-deficient medium.
Unit Definition【单位定义】
One unit will liberate 1.0 μmole of CO2 from L-tyrosine per min at pH 5.5 at 37 ℃.
