ID 1.3.1.123 DE 7-epi-iridoid synthase. CA (R)-8-oxocitronellyl enol + NADP(+) = (6E)-8-oxogeranial + H(+) + NADPH. CC -!- The enzyme, characterized from the plant Antirrhinum majus CC (snapdragon), is involved in biosynthesis of 7-epi-iridoids such as CC antirrhinoside. CC -!- The enzyme catalyzes the stereospecific reduction of 8-oxogeranial, CC forming an unstable product that in the absence of additional cylases CC undergoes spontaneous cyclization to (-)-cis,trans-nepetalactol. cf.
