Momilactone-A synthase (EC 1.1.1.295 momilactone A synthase OsMAS) is an enzyme with system name 3beta-hydroxy-9beta-pimara-715-diene-196beta-olide:NAD(P)+ oxidoreductase. This enzyme catalyses the following chemical reaction 3beta-hydroxy-9beta-pimara-715-diene-196beta-olide + NAD(P)+ momilactone A + NAD(P)H + H+The rice phytoalexin momilactone A is a diterpenoid secondary metabolite that is involved in the defense mechanism of the plant.
