CC -!- FUNCTION: Short chain dehydrogenase/reductase; part of the gene cluster
CC that mediates the biosynthesis of the tetrahydroxanthone dimer
CC secalonic acid D (PubMed:30996871, PubMed:33891392). The pathway begins
CC with the synthesis of atrochrysone thioester by the polyketide synthase
CC AacuL (Probable). The atrochrysone carboxyl ACP thioesterase AacuM then
CC breaks the thioester bond and releases the atrochrysone carboxylic acid
CC from AacuL (Probable). Atrochrysone carboxylic acid is decarboxylated
CC by the decarboxylase AacuI, and oxidized by the anthrone oxygenase
CC AacuG to yield emodin (Probable). Emodin is then reduced to emodin
CC hydroquinone by a yet unidentified oxidoreductase (Probable). A-ring
CC reduction by the short chain dehydrogenase AacuN, dehydration by the
CC scytalone dehydratase-like protein AacuK and probable spontaneous re-
CC oxidation, results in overall deoxygenation to chrysophanol
CC (PubMed:33891392). Baeyer-Villiger oxidation by the Baeyer-Villiger
CC monooxygenase (BVMO) AacuH then yields monodictyphenone
CC (PubMed:33891392). Monodictyphenone is transformed into compounds with
CC the tetrahydroxanthone skeleton via methylesterification by the
CC methyltransferase AacuQ, followed by the action of the flavin-dependent
CC monooxygenase AacuC, the isomerase AacuP, and the short chain
CC dehydrogenase/reductase AacuF or AacuD (PubMed:33891392). AacuF and
CC AacuD should accept the same compound as a substrate but perform the
CC ketoreduction with a different stereoselectivity, thus yielding
CC blennolides B and A, respectively (PubMed:33891392). In the final step
CC of the biosynthesis, the cytochrome P450 monooxygenase AacuE accepts
CC blennolide B and/or blennolide A to conduct the dimerization reaction
CC to furnish the tetrahydroxanthone dimers, secalonic acids D, B, and F
CC (PubMed:33891392). {ECO:0000269|PubMed:30996871,
CC ECO:0000269|PubMed:33891392, ECO:0000305|PubMed:33891392}.
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000305|PubMed:30996871}.
CC -!- BIOTECHNOLOGY: Secalonic acids show unprecedented anticancer activities
CC against various human cancer cells and might be interesting for further
CC derivatization, targeting diseases such as cancer.

CC ECO:0000269|PubMed:30678274, ECO:0000269|PubMed:33015446}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. {ECO:0000305}.
