Strictosidine Synthase
From Proteopedia
|
strictosidine synthase (EC 4.3.3.2) is an enzyme that catalyzes the chemical reaction
3-alpha(S)-strictosidine + H2O \rightleftharpoons tryptamine + secologanin
Thus, the two substrates of this enzyme are 3-alpha(S)-strictosidine and H2O, whereas its two products are tryptamine 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 3-alpha(S)-strictosidine tryptamine-lyase (secologanin-forming). Other names in common use include strictosidine synthetase, STR, and 3-alpha(S)-strictosidine tryptamine-lyase. This enzyme participates in terpenoid biosynthesis and indole and ipecac alkaloid biosynthesis.
