Description
This plant enzyme catalyses the penultimate step in the biosynthesis of the pterocarpin phytoalexins medicarpin and maackiain. This activity was previously classified as part of EC 1.1.1.246, pterocarpin synthase, which is now known to be catalysed by two enzymes, vestitone reductase and EC 4.2.1.139, medicarpin synthase
