Protein attributes

Sequence length	450 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the first step of ergot alkaloid biosynthesis. Ergot alkaloids, which are produced by endophyte fungi, can enhance plant host fitness, but also cause livestock toxicosis to host plants. Ref.1
Catalytic activity	Dimethylallyl diphosphate + L-tryptophan = diphosphate + 4-(3-methylbut-2-enyl)-L-tryptophan.
Pathway	Alkaloid biosynthesis; ergot alkaloid biosynthesis.
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the tryptophan dimethylallyltransferase family.
