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

The biogenic amine tyramine (TA) is a potent diuretic factor when applied to the Malpighian tubule (MT) of Drosophila melanogaster, stimulating both urine production and transepithelial chloride conductance. Isolated MTs can respond not only to TA but also to its

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.
