Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	This is a key enzyme of plant metabolism catalyzing the first reaction in the biosynthesis from L-phenylalanine of a wide variety of natural products based on the phenylpropane skeleton.
Catalytic activity	L-phenylalanine = trans-cinnamate + ammonia.
Pathway	Phenylpropanoid metabolism; cinnamic acid biosynthesis; trans-cinnamic acid from L-phenylalanine: step 1/1.
Subcellular location	Cytoplasm Probable.
Post-translational modification	Contains an active site 4-methylidene-imidazol-5-one (MIO), which is formed autocatalytically by cyclization and dehydration of residues Ala-Ser-Gly By similarity.
Sequence similarities	Belongs to the PAL/histidase family.
