General annotation (Comments)

Function

Oxidosqualene cyclase involved in the biosynthesis of bryonolic acid. Converts oxidosqualene to isomultiflorenol. Ref.1

Catalytic activity

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

Miscellaneous

In cultured cells, IMS1 mRNA expression is high between days 16 and 20 and precedes the accumulation of bryonolic acid.

Sequence similarities

Belongs to the terpene cyclase/mutase family.

Contains 4 PFTB repeats.
