Protein: Oryzalexin D synthase (EC 1.14.14.112) (EC 1.14.14.123) (Cytochrome P450 76M8) (Ent-cassadiene C11-alpha-hydroxylase 2) (Q6YTF1)
Organism: Oryza sativa subsp. japonica (Rice)
Function: Enzyme of the diterpenoid metabolism involved in the biosynthesis of both phytocassane and the oryzalexin class of phytoalexins. Can hydroxylate syn-pimaradiene, ent-pimaradiene, ent-sandaracopimaradiene, ent-isokaurene, ent-kaurene, and ent-cassadiene, but no activity with syn-stemodene, syn-stemarene, syn-labdatriene, C11-alpha-hydroxy-ent-cassadiene or syn-pimadien-19-oic acid as substrates. Hydroxylates 3-alpha-hydroxy-ent-sandaracopimaradiene at C-7-beta, resulting in a 3-alpha,7-beta-diol corresponding to oryzalexins D.
Subcellular location: Membrane {ECO:0000305}; Single-pass membrane protein {ECO:0000305}.
