CC   -!- FUNCTION: Short chain dehydrogenase; part of the gene cluster that
CC       mediates the biosynthesis of anditomin, a fungal meroterpenoid
CC       (PubMed:25216349). The first step of the pathway is the synthesis of
CC       3,5-dimethylorsellinic acid (DMOA) by the polyketide synthase andM
CC       (PubMed:25216349). DMOA is then converted to the phthalide compound
CC       5,7-dihydroxy-4,6-dimethylphthalide (DHDMP) by the cytochrome P450
CC       monooxygenase andK, which is further prenylated by the
CC       prenyltransferase andD to yield farnesyl-DHDMP (PubMed:25216349).
CC       Further epoxidation by the FAD-dependent monooxygenase andE leads to
CC       epoxyfarnesyl-DHDMP (PubMed:25216349). The next step involves the
CC       terpene cyclase andB that converts epoxyfarnesyl-DHDMP into preandiloid
CC       A through opening of the epoxide ring followed by the cyclization of
CC       the farnesyl moiety (PubMed:25216349). Preandiloid A is in turn
CC       oxidized at the C-3 hydroxyl group to yield preandiloid B by the
CC       dehydrogenase andC (PubMed:25216349). The dioxygenase andA is solely
CC       responsible for the dehydrogenation of preandiloid B leading to the
CC       enone preandiloid C, as well as for the intriguing structural
CC       rearrangement to generate the bicyclo[2.2.2]octane core, transforming
CC       preandiloid C into andiconin (PubMed:25216349). FAD-binding
CC       monooxygenase andJ then produces andilesin D which is reduced by
CC       dehydrogenase andI to yield andilesin A (PubMed:25216349). Action of
CC       acetyltransferase andG followed by a spontaneous acetate elimination
CC       leads then to andilesin B, which is in turn substrate of the short
CC       chain dehydrogenase andH to yield andilesin C (PubMed:25216349).
CC       Finally, the dioxygenase andF catalyzes the transformation of andilesin
CC       C to anditomin (PubMed:25216349). {ECO:0000269|PubMed:25216349}.
CC   -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC       {ECO:0000269|PubMed:25216349}.
CC   -!- DISRUPTION PHENOTYPE: Impairs the synthesis of anditomin but
CC       accumulates andilesin D (PubMed:25216349).
CC       {ECO:0000269|PubMed:25216349}.
CC   -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC       family. {ECO:0000305}.
