   4.2.1.92 | evolution |
allene oxide synthases, like hydroperoxide lyases and divinyl ether synthases belong to the CYP74 family of cytochrome P450 enzymes. These enzymes rearrange fatty acid hydroperoxides differently, sharing an epoxyallylic radical as a common intermediate |

AOS is a non-classical cytochrome P450, which, like other CYP74 enzymes, does not require molecular oxygen and NADPH-dependent P450 reductase |

FOXB_01332 is a linoleate 9-DOX with homology to animal heme peroxidases and a 9-dioxygenase-allene oxide synthase fusion protein. The conserved Tyr-(His/Arg)-Trp-His motif contains a Phe instead of the catalytic Tyr residue, which is oxidized by the heme to a radical that performs the hydrogen abstraction of LDS and COX, the replacement of Phe 416 with Trp does not affect the product profile of FOXB_01332 |

| 4.2.1.92 | evolution |
hydroperoxide lyases are classified in the cytochrome P450 family and more particularly in the two subfamilies CYP74B (13-HPL) and CYP74C (9-HPL and 9/13-HPL) |

loss-of-function mutant hpl3-1 produces disease-resembling lesions spreading through the whole leaves. Mutant hpl3-1 plants exhibit enhanced induction of jasmonic acid, trypsin proteinase inhibitors and other volatiles, but decreased levels of green leaf volatiles including (Z)-3-hexen-1-ol. Mutant hpl3-1 plants are more attractive to a BPH egg parasitoid, Anagrus nilaparvatae, than the wild-type, most likely as a result of increased release of BPH-induced volatiles. Mutant hpl3-1 plants also show increased resistance to bacterial blight (Xanthomonas oryzae pv. oryzae) |

silencing HPL in wild-type Solanum lycopersicum increases potato aphid (Macrosiphum euphorbiae) host preference and reproduction on 5-week-old plants but has no influence on 3-week-old plants. Silencing HPL in spr2 mutants does not compromise this aphid resistance. Moreover, a mutation in the FAD7 gene in Arabidopsis thaliana also confers resistance to the green peach aphid (Myzus persicae) in a genetic background that carries a null mutation in HPL |
