货号：zk7424

英文名: Tyrosine Decarboxylase, Apoenzyme
级别: Activity ≥0.2 U/mg
储存: 冷冻（-20℃）
规格:250 MG 1G

概述:

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 apoenzyme prepared from cells grown on a vitamin B6 deficient medium pyridoxal phosphate may be determined. The HOLOenzyme may be used to determine tyrosine, phenylalanine and dihydroxyphenylalanine either manometrically or colorimetrically.
