Names and origin

Protein attributes

Sequence length767 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Oxidosqualene cyclase that generates friedelin, a triterpenoid product with the maximum number of rearrangements possible. Friedelin is probably required to coat the leaf exterior as defense compound against pathogens or herbivores. Ref.1

Catalytic activity

(3S)-2,3-epoxy-2,3-dihydrosqualene = friedelin. Ref.1

Tissue specificity

Expressed only in the epidermal cells on both sides of the leaf and not in internal leaf tissues. Ref.1

Sequence similarities

Belongs to the terpene cyclase/mutase family.

Contains 2 PFTB repeats.
