In enzymology, a pterocarpin synthase (EC 1.1.1.246) is an enzyme that catalyzes the chemical reaction
medicarpin + NADP+ + H2O
⇌
{\displaystyle \rightleftharpoons }
vestitone + NADPH + H+
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.
