Involved in the biosynthesis of capsidiol. Catalyzes the successive and independent hydroxylations at the C1 and C3 positions of 5-epiaristolochene. The second hydroxylation step is 8-fold more efficient than the first hydroxylation reaction. Capable of utilizing premnaspirodiene as a substrate. (+)-5-epi-aristolochene + 2 O2 + 2 reduced [NADPH--hemoprotein reductase] = capsidiol + 2 H(+) + 2 H2O + 2 oxidized [NADPH--hemoprotein reductase] Inhibited by ancymidol and ketoconazole. Optimum pH is 7.5. Up-regulated 6 to 9 hours after elicitor-treatment and then declines by 12 hours. Belongs to the cytochrome P450 family.
