Tyrosine Decarboxylase
Source:
Streptococcus faecalis (NCTC6783)
CAS:
9002-09-9
EC:
4.1.1.25
I.U.B.: 4.1.1.25
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.
Unit Definition
One Unit yields 1µmole of CO2 per minute from L-tyrosine at 37°C, pH 5.5. The APOenzyme activity is measured in the presence of excess pyridoxal phosphate.
