CC   -!- FUNCTION: Short-chain dehydrogenase/reductase; part of the core
CC       atranone cluster (CAC) which products are predicted to catalyze most or
CC       all 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   -!- PATHWAY: Mycotoxin biosynthesis. {ECO:0000305|PubMed:25015739}.
CC   -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC       family. {ECO:0000305}.
