Accepted name: linalool 8-monooxygenase

Reaction: linalool + 2 [reduced NADPH—hemoprotein reductase] + 2 O2 = (6E)-8-oxolinalool + 2 [oxidized NADPH—hemoprotein reductase] + 3 H2O (overall reaction)
(1a) linalool + [reduced NADPH—hemoprotein reductase] + O2 = (6E)-8-hydroxylinalool + [oxidized NADPH—hemoprotein reductase] + H2O
(1b) (6E)-8-hydroxylinalool + [reduced NADPH—hemoprotein reductase] + O2 = (6E)-8-oxolinalool + [oxidized NADPH—hemoprotein reductase] + 2 H2O
