General annotation (Comments)

Function

Sesquiterpene synthase that catalyzes the formation of vetispiradiene from trans,trans-farnesyl diphosphate. The initial internal cyclization produces the monocyclic intermediate germacrene A.

Catalytic activity

(2E,6E)-farnesyl diphosphate = vetispiradiene + diphosphate. Ref.1

Cofactor

Binds 3 magnesium ions per subunit By similarity.

Pathway

Secondary metabolite biosynthesis; terpenoid biosynthesis.

Subcellular location

Cytoplasm Probable.

Induction

By elicitor from R.solani. Ref.1

Domain

The Asp-Asp-Xaa-Xaa-Asp/Glu (DDXXD/E) motif is important for the catalytic activity, presumably through binding to Mg2+.

Sequence similarities

Belongs to the terpene synthase family. Tpsa subfamily.
