CC -!- FUNCTION: Acetyltransferase; part of the gene cluster that mediates the
CC biosynthesis of botrydial (PubMed:14651630, PubMed:19035644,
CC PubMed:27529428). Botrydial is necessary for colonization of plant
CC tissue by the T4 strain (PubMed:19035644). It is a strain-dependent
CC virulence factor since highly aggressive strains like SAS56 or B05
CC still retain substantial virulence when botrydial synthesis is
CC impaired, since they produce also botcinic acid (PubMed:15986930). The
CC first step of botrydial biosynthesis is performed by the sesquiterpene
CC synthase BOT2 which catalyzes the cyclization of farnesyl diphosphate
CC (FPP) to presilphiperfolan-8-beta-ol (PSP) (PubMed:19035644,
CC PubMed:19476353). The cytochrome P450 monooxygenase BOT4 then catalyzes
CC the hydroxylation at C-4 to give a probotryane intermediate
CC (PubMed:27529428, PubMed:28617493). Acetylation of the hydroxyl at C-4
CC is carried out by the acetyltransferase BOT5, followed by the combined
CC action of the P450 monooxygenases BOT3 and BOT1, to yield finally the
CC glycol, via the regio- and stereospecific hydroxylations at C-10 and C-
CC 15 of the 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 ECO:0000269|PubMed:27721016, ECO:0000269|PubMed:28617493}.
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000305|PubMed:27529428}.
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 -!- SIMILARITY: Belongs to the plant acyltransferase family. {ECO:0000305}.
