Native Streptococcus faecalis L-Tyrosine Decarboxylase Apoenzyme


Cat No.
NATE-0420
Description
In enzymology, a tyrosine decarboxylase (EC 4.1.1.25) is an enzyme that catalyzes the chemical reaction:L-tyrosine↔ tyramine + CO2. Hence, this enzyme has one substrate, L-tyrosine, and two products, tyramine and carbon dioxide. This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. This enzyme participates in tyrosine metabolism and alkaloid biosynthesis. It employs one cofactor, pyridoxal phosphate.

Streptococcus faecalis
Applications
L-Tyrosine decarboxylase apoenzyme from Strept oc occus faecalis has been used in a study to purify and characterize tyrosine decarboxylase and aromatic-L-amino-acid decarboxylase. L-Tyrosine decarboxylase apoenzyme from Strept oc occus faecalis has also been used in a study to investigate the stereospecificity of sodium borohydride reduction of tyrosine decarboxylase.
