CC   -!- FUNCTION: O-acetyltransferase; part of the gene cluster that mediates
CC       the biosynthesis of PR-toxin, a bicyclic sesquiterpene belonging to the
CC       eremophilane class and acting as a mycotoxin (PubMed:24239699). The
CC       first step of the pathway is catalyzed by the aristolochene synthase
CC       which performs the cyclization of trans,trans-farnesyl diphosphate
CC       (FPP) to the bicyclic sesquiterpene aristolochene (PubMed:24239699).
CC       Following the formation of aristolochene, the non-oxygenated
CC       aristolochene is converted to the trioxygenated intermediate
CC       eremofortin B, via 7-epi-neopetasone (PubMed:24239699). This conversion
CC       appears to involve three enzymes, a hydroxysterol oxidase-like enzyme,
CC       the quinone-oxidase prx3 that forms the quinone-type-structure in the
CC       bicyclic nucleus of aristolochene with the C8-oxo group and the C-3
CC       hydroxyl group, and the P450 monooxygenase prx9 that introduces the
CC       epoxide at the double bond between carbons 1 and 2 (PubMed:24239699)
CC       (By similarity). No monoxy or dioxy-intermediates have been reported to
CC       be released to the broth, so these three early oxidative reactions may
CC       be coupled together (PubMed:24239699). Eremofortin B is further
CC       oxidized by another P450 monooxygenase, that introduces a second
CC       epoxide between carbons 7 and 11 prior to acetylation to eremofortin A
CC       by the acetyltransferase prx11 (By similarity). The second epoxidation
CC       may be performed by a second P450 monooxygenase (PubMed:24239699).
CC       After the acetylation step, eremofortin A is converted to eremofortin C
CC       and then to PR-toxin (PubMed:24239699). First the conversion of
CC       eremofortin A to eremofortin C proceeds by oxidation of the side chain
CC       of the molecule at C-12 and is catalyzed by the short-chain
CC       oxidoreductase prx1 (PubMed:24239699). The cytochrome P450
CC       monooxygenase prx8 also plays a role in this step (By similarity). The
CC       primary alcohol formed at C-12 is finally oxidized by the short-chain
CC       alcohol dehydrogenase prx4 that forms PR-toxin (PubMed:24239699).

CC   -!- PATHWAY: Sesquiterpene biosynthesis. {ECO:0000305|PubMed:24239699}.
CC   -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:Q4WZ64}.
CC   -!- INDUCTION: Expression and the subsequent production of PR-toxin take
CC       place under static culture conditions (oxygen limited), whereas no
CC       expression of the PR-toxin genes occurs under the strongly aerated
CC       conditions required for optimal penicillin production
CC       (PubMed:24239699). There is a negative control of the transcription of
CC       the PR-toxin genes by the penicillin biosynthesis gene product(s), or
CC       by a regulatory peptide encoded by a small ORF inside the penicillin
CC       gene cluster (PubMed:24239699). {ECO:0000269|PubMed:24239699}.
CC   -!- SIMILARITY: Belongs to the fumigaclavine B O-acetyltransferase family.
CC       {ECO:0000305}.
