CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC mediates the biosynthesis of botrydial (PubMed:14651630,
CC PubMed:19476353, PubMed:27529428). Botrydial is necessary for
CC colonization of plant tissue by the T4 strain (PubMed:19035644). It is
CC a strain-dependent virulence factor since highly aggressive strains
CC like SAS56 or B05 still retain substantial virulence when botrydial
CC synthesis is impaired, since they produce also botcinic acid
CC (PubMed:15986930). The first step of botrydial biosynthesis is
CC performed by the sesquiterpene synthase BOT2 which catalyzes the
CC cyclization of farnesyl diphosphate (FPP) to presilphiperfolan-8-beta-
CC ol (PSP) (PubMed:19035644, PubMed:19476353). The cytochrome P450
CC monooxygenase BOT4 then catalyzes the hydroxylation at C-4 to give a
CC probotryane intermediate (PubMed:27529428, PubMed:28617493).
CC Acetylation of the hydroxyl at C-4 is carried out by the
CC acetyltransferase BOT5, followed by the combined action of the P450
CC monooxygenases BOT3 and BOT1, to yield finally the glycol, via the
CC regio- and stereospecific hydroxylations at C-10 and C-15 of the
CC probotryane intermediates, respectively (PubMed:15986930,
CC PubMed:27529428). The cleavage of the C10-C15 bond of probotryane
CC skeleton is an intriguing and chemically important reaction, which
CC could be mediated by some of the monooxygenases or by a combination of
CC them (PubMed:27529428). It is possible that either BOT3 or BOT1 would
CC oxidize either the 10- or the 15-hydroxy group to the hydroperoxide
CC derivative, which would then undergo heterolytic fragmentation to give
CC the dialdehyde botrydial (PubMed:27529428). Finally, the dehydrogenase
CC BOT7 might be involved in the conversion of botrydial to
CC dihydrobotrydial (PubMed:27721016). {ECO:0000269|PubMed:14651630,
CC ECO:0000269|PubMed:15986930, ECO:0000269|PubMed:19035644,
CC ECO:0000269|PubMed:19476353, ECO:0000269|PubMed:27529428,

CC Evidence={ECO:0000250|UniProtKB:P04798};
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000269|PubMed:27529428, ECO:0000269|PubMed:28617493}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Single-pass membrane
CC protein {ECO:0000255}.
CC -!- INDUCTION: The botrydial biosynthesis cluster genes are co-regulated by
CC the Ca(2+)/calcineurin signal transduction pathway, which is under the
CC control of the alpha subunit BCG1 of a heterotrimeric G protein
CC (PubMed:19035644). Expression of the cluster is also positively
CC regulated by the cluster-specific transcription factor BOT6
CC (PubMed:27721016). {ECO:0000269|PubMed:19035644,
CC ECO:0000269|PubMed:27721016}.
CC -!- DISRUPTION PHENOTYPE: Abolishes the production of botrydial and
CC accumulates 5-hydroxy-7-(oct-2-enoyl)botrylactone, 6-beta-hydroxy-7-
CC deoxybo-trylactone, cinbotolide B, and cinbotolide C (PubMed:27529428).
CC {ECO:0000269|PubMed:27529428}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
