Deacetylisoipecoside synthase

In enzymology, a deacetylisoipecoside synthase (EC 4.3.3.3) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are deacetylisoipecoside and H₂O, whereas its two products are dopamine and secologanin.

This enzyme belongs to the family of lyases, specifically amine lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is deacetylisoipecoside dopamine-lyase (secologanin-forming). This enzyme is also called deacetylisoipecoside dopamine-lyase. This enzyme participates in indole and ipecac alkaloid biosynthesis.
