Component of the monoterpenoid pyrethrins biosynthesis; pyrethrins are widely used plant-derived pesticide (PubMed:30468448). Mediates the conversion of trans-chrysanthemal into trans-chrysanthemic acid (PubMed:29122986). Can also use octanal, hept-2-enal, dodecanal, citral, farnesal, citronellal and perillyl aldehyde as substrates (PubMed:29122986). an aldehyde + H2O + NAD(+) = a carboxylate + 2 H(+) + NADH an aldehyde + H2O + NADP(+) = a carboxylate + 2 H(+) + NADPH H2O + NADP(+) + octanal = 2 H(+) + NADPH + octanoate (1R,3R)-chrysanthemal + H2O + NAD(+) = (1R,3R)-chrysanthemate + 2 H(+) + NADH (1R,3R)-chrysanthemal + H2O + NADP(+) = (1R,3R)-chrysanthemate + 2 H(+) + NADPH (E)-hept-2-enal + H2O + NADP(+) = (E)-hept-2-enoate + 2 H(+) + NADPH dodecanal + H2O + NADP(+) = dodecanoate + 2 H(+) + NADPH citral + H2O + NADP(+) = 3,7-dimethylocta-2,6-dienoate + 2 H(+) + NADPH H2O + NADP(+) + perillyl aldehyde = 2 H(+) + NADPH + perillate (2E,6E)-farnesal + H2O + NADP(+) = (2E,6E)-farnesoate + 2 H(+) + NADPH (S)-(-)-citronellal + H2O + NADP(+) = (S)-(-)-citronellate + 2 H(+) + NADPH kcat is 0.11 sec(-1) with trans-chrysanthemal as substrate (in the presence of NAD(+)) (PubMed:29122986). kcat is 0.096 sec(-1) with trans-chrysanthemal as substrate (in the presence of NADP(+)) (PubMed:29122986). kcat is 0.09 sec(-1) with NAD(+) as substrate (in the presence of trans-chrysanthemal) (PubMed:29122986). kcat is 0.086 sec(-1) with NADP(+) as substrate (in the presence of trans-chrysanthemal) (PubMed:29122986). Isoprenoid biosynthesis. Homotetramer. Expressed in flowers and disk florets. Belongs to the aldehyde dehydrogenase family.
