Protein: Oryzalexin E synthase (EC 1.14.14.122) (Cytochrome P450 76M6) (Q6Z5I7)
Organism: Oryza sativa subsp. japonica (Rice)
Function: Enzyme of the diterpenoid metabolism involved in the biosynthesis of the oryzalexin class of phytoalexins. Can use ent-sandaracopimaradien and syn-stemodene as substrates, but no activity with syn-stemoden-19-oic acid. Hydroxylates 3-alpha-hydroxy-ent-sandaracopimaradiene at C-9-beta, resulting in a 3-alpha,9-beta-diol corresponding to oryzalexins E.
Subcellular location: Membrane {ECO:0000255}; Single-pass membrane protein {ECO:0000255}.
