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.
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
