In enzymology, a tropinone reductase II (EC 1.1.1.236) is an enzyme that catalyzes the chemical reaction
- pseudotropine + NADP+ tropinone + NADPH + H+
Thus, the two substrates of this enzyme are pseudotropine and NADP+, whereas its 3 products are tropinone, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is pseudotropine:NADP+ 3-oxidoreductase. Other names in common use include tropinone (psi-tropine-forming) reductase, pseudotropine forming tropinone reductase, tropinone reductase (ambiguous), and TR-II. This enzyme participates in alkaloid biosynthesis ii.
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1AE1, 1IPE, 1IPF, 1XHL, 2AE1, and 2AE2.
