Pterocarpin synthase

In enzymology, a pterocarpin synthase (EC 1.1.1.246) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are medicarpin, NADP⁺, and H₂O, whereas its 3 products are vestitone, 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 medicarpin:NADP⁺ 2'-oxidoreductase. This enzyme is also called pterocarpan synthase. This enzyme participates in isoflavonoid biosynthesis.
