Application
L-Tyrosine decarboxylase from Streptococcus faecalis has been used in a study to isolate and identify the carbonyl-active site of diamine oxidase by gas chromatographic mass spectrometry. L-Tyrosine decarboxylase from Streptococcus faecalis has also been used in a study to investigate the adsorption of Streptococcus faecalis on diatomite carriers for use in biotransformations.
Other Notes
Dried cells from which activity can be extracted.
Unit Definition
One unit will cause the decomposition of 1.0 μmole of L-tyrosine per min at pH 6.2 at 37 °C.

Adsorption of cells on particulate carriers is potentially one of the most cost-effective immobilization techniques available. Diatomite carriers, such as Celite, have desirable physical properties, are inexpensive, and are suitable for both mycelial and bacterial systems. This work investigated the

An adduct with phenylhydrazine was formed with the purified pig kidney diamine oxidase and in parallel with the l-tyrosine decarboxylase from Streptococcus faecalis. The labeled enzymes were hydrolyzed by chemical hydrolysis and the adducts released by hydrolysis were isolated and

The microbial decarboxylation of some amino acids leads to the undesirable presence of biogenic amines in foods. One of the most abundant and frequent biogenic amines found in fermented foods is tyramine, which is produced by the decarboxylation of tyrosine.

The δ(18)O value of the p-hydroxy group of L-tyrosine depends on the biosynthesis by plants or animals, respectively. In animal proteins it reflects the diet and is therefore an absolute indicator for illegal feeding with meat and bone meal. The
