English name : L-Tyrosine carboxy-lyase Apoenzyme; L-Tyrosine Decarboxylase Apoenzyme from Streptococcus faecalis
Level : BR
Source: Streptococcus faecalis enzyme protein
Vitality : Activaties to) 0.1 units per mg with 5ug of B6
Dynamic definition of : One unit yields 1uM of CO2 from L-tyrosine per min at pH 5.5 at 37 ° C
Product description :. 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.
Use: Biochemical studies
