	4.1.1.105
Description	L-tryptophan decarboxylase
Alternative names	psiD (gene name); TDC (gene name)
Catalyzed reaction	L-tryptophan = tryptamine + CO(2).
Cofactor	Pyridoxal-phosphate or pyruvate.
Comments	-!- The enzyme has been characterized from bacteria, plants, and fungi. Unlike EC 4.1.1.28, aromatic-L-amino-acid decarboxylase, this enzyme is specific for L-typtophan.
	The L-Trp decarboxylase from the fungus Psilocybe (involved in the biosynthesis of the psychotropic psilocybin) is PLP-independent and presumably requires a pyruvoyl group.
