Description Alanine decarboxylase (4.1.1.-)
Catalyzed reaction L-alanine = ethylamine + CO(2).
Cofactor Pyridoxal-phosphate.
A very specialized decarboxylase described in Camellia sinensis (tea plant) and apparently required to provide ethylamine for the production of the non-proteinogenic amino acid L-theanine.
Theanine is found primarily in particular plant (Camellia and strictly relatetd species) and in some fungi (Xerocomus badius).
