CC   -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC       mediates the biosynthesis of abscisic acid (ABA), a phytohormone that
CC       acts antagonistically toward salicylic acid (SA), jasmonic acid (JA)
CC       and ethylene (ETH) signaling, to impede plant defense responses
CC       (PubMed:15240257, PubMed:16820452). The first step of the pathway
CC       catalyzes the reaction from farnesyl diphosphate to alpha-
CC       ionylideneethane performed by the alpha-ionylideneethane synthase aba3
CC       via a three-step reaction mechanism involving 2 neutral intermediates,
CC       beta-farnesene and allofarnesene (PubMed:30226766). The cytochrome P450
CC       monooxygenase aba1 might then be involved in the conversion of alpha-
CC       ionylideneethane to alpha-ionylideneacetic acid (Probable). Alpha-
CC       ionylideneacetic acid is further converted to abscisic acid in 2 steps
CC       involving the cytochrome P450 monooxygenase aba2 and the short-chain
CC       dehydrogenase/reductase aba4, via the intermediates 1'-deoxy-ABA or
CC       1',4'-trans-diol-ABA, depending on the order of action of these 2
CC       enzymes (Probable). Aba2 is responsible for the hydroxylation of carbon
CC       atom C-1' and aba4 might be involved in the oxidation of the C-4'
CC       carbon atom (PubMed:16820452). {ECO:0000269|PubMed:15240257,
CC       ECO:0000269|PubMed:16820452, ECO:0000269|PubMed:30226766,
CC       ECO:0000305|PubMed:16820452}.
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413;
CC         Evidence={ECO:0000250|UniProtKB:P04798};
CC   -!- PATHWAY: Hormone biosynthesis. {ECO:0000269|PubMed:16820452}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC       protein {ECO:0000255}.
CC   -!- INDUCTION: Expression is persistently induced 60 min after the addition
CC       of the ABA precursor mevalonic acid (MVA) to the medium.
CC       {ECO:0000269|PubMed:16820452}.
CC   -!- DISRUPTION PHENOTYPE: Impairs the production of abscisic acid (ABA) and
CC       leads to the accumulation of 1'-deoxy-ABA.
CC       {ECO:0000269|PubMed:16820452}.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
