CC -!- FUNCTION: Cytochrome P450 monooxygenase; part of the core atranone
CC cluster (CAC) which products are predicted to catalyze most or all
CC steps of mycotoxin atranone synthesis, starting from geranylgeranyl
CC pyrophosphate (GGPP) (PubMed:25015739). The initial cyclization of GGPP
CC to dolabellane is probably performed by the terpene cyclase ATR13
CC (PubMed:25015739). The Baeyer-Villiger oxidation near the end of the
CC atranone synthesis, which converts atranones D and E to atranones F and
CC G is predicted to be catalyzed by the monooxygenase ATR8
CC (PubMed:25015739). Of the CAC's other predicted gene products, the
CC reducing PKS ATR6 might synthesize a polyketide chain
CC (PubMed:25015739). This polyketide is probably transferred onto the
CC atranone backbone by the polyketide transferase ATR5 (By similarity).
CC Other predicted CAC products include 4 oxygenases (ATR2, ATR3, ATR4,
CC and ATR14), 3 short-chain reductases (ATR7, ATR9, and ATR10), and a
CC methyltransferase (ATR12) (PubMed:25015739). These may all be involved
CC in the various steps of atranone biosynthesis, although their specific
CC roles must await experimental determination (PubMed:25015739).

CC Evidence={ECO:0000250|UniProtKB:P04798};
CC -!- PATHWAY: Mycotoxin biosynthesis. {ECO:0000305|PubMed:25015739}.
CC -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
