Component of the monoterpenoid pyrethrins biosynthesis; pyrethrins are widely used plant-derived pesticide (PubMed:30468448). Mediates the conversion of trans-chrysanthemol into trans-chrysanthemal (PubMed:29122986). (R,R)-chrysanthemol + NAD(+) = (1R,3R)-chrysanthemal + H(+) + NADH NAD(+) + nerol = H(+) + NADH + neral (S)-(-)-citronellol + NAD(+) = (S)-(-)-citronellal + H(+) + NADH NAD(+) + perillyl alcohol = H(+) + NADH + perillyl aldehyde (6E)-8-hydroxygeraniol + NAD(+) = (6E)-8-hydroxygeranial + H(+) + NADH (2E)-geraniol + NAD(+) = (2E)-geranial + H(+) + NADH Binds 2 Zn(2+) ions per subunit. kcat is 0.75 sec(-1) with trans-chrysanthemol as substrate (in the presence of NAD(+)) (PubMed:29122986). kcat is 0.64 sec(-1) with NAD(+) as substrate (in the presence of trans-chrysanthemol) (PubMed:29122986). Isoprenoid biosynthesis. Homodimer. Expressed in flowers and disk florets. Belongs to the zinc-containing alcohol dehydrogenase family. Class-IV subfamily.
