CC   -!- FUNCTION: Cytochrome P450 monooxygenase; part of the gene cluster that
CC       mediates the biosynthesis of botrydial (PubMed:14651630,
CC       PubMed:19035644, 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       Name=heme; Xref=ChEBI:CHEBI:30413;
CC         Evidence={ECO:0000250|UniProtKB:P04798};
CC   -!- PATHWAY: Secondary metabolite biosynthesis.
CC       {ECO:0000269|PubMed:27529428}.
CC   -!- SUBCELLULAR LOCATION: Membrane {ECO:0000255}; Multi-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:14651630, PubMed:19035644). Expression of the cluster is also
CC       positively regulated by the cluster-specific transcription factor BOT6
CC       (PubMed:27721016). {ECO:0000269|PubMed:14651630,
CC       ECO:0000269|PubMed:19035644, ECO:0000269|PubMed:27721016}.
CC   -!- DISRUPTION PHENOTYPE: Abolishes the production of botrydial and
CC       accumulates high levels of the biosynthetic intermediate beta-acetoxy-
CC       15-alpha--hydroxyprobotryane and small amounts of botcinin A
CC       (PubMed:27529428). {ECO:0000269|PubMed:27529428}.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
