活力 Activaties to>0.1 units per mg with 5ug of B6
活力定义 One unit yields 1uM of CO2 from L-tyrosine per min at pH 5.5 at 37 °C
酪氨酸脱羧酶产品描述 Dried cells grown in B6 deficient media.The apoenzyme activity is measured in the presence of excess pyridoxal phosphate. Tyrosine decarboxylase catalyzes the removal of the carboxyl group from tyrosine to produce tyramine and carbon dioxide.Pyridoxal 5-phosphate is a necessary cofactor.By using the apoezyme prepared from cells grown on a vitamin B6 deficient medium.Pyridoxal phosphate may be determined.The HOLO enzyme may be used to determine tyrosine.Phenylalanine and dihydroxyphenylalanine either manometrically or colorimetrically.
