CC -!- FUNCTION: Short-chain dehydrogenase/reductase; part of the gene cluster
CC that mediates the biosynthesis of eupenifeldin, a bistropolone
CC meroterpenoid that acts as an antitumor agent (PubMed:30980906). The
CC first step of eupenifeldin biosynthesis is the biosynthesis of 3-
CC methylorcinaldehyde performed by the non-reducing polyketide synthase
CC eupA (PubMed:30980906). Oxidative dearomatization of 3-
CC methylorcinaldehyde likely catalyzed by the FAD-dependent monooxygenase
CC eupB is followed by oxidative ring expansion by the 2-oxoglutarate-
CC dependent dioxygenase eupC to provide the first tropolone metabolite,
CC tropolone stipitaldehyde (Probable). In parallel, generation of
CC sesquiterpene alpha-humulene from farnesylpyrophosphate (FPP) is
CC catalyzed by the terpene cyclase eupE (PubMed:30980906). The cytochrome
CC P450 monooxygenase eupD then hydroxylates humulene to humulenol
CC (PubMed:30980906). The putative Diels-Alderase eupF probably catalyzes
CC the formation of the tropolone-humulene skeleton by linking humulenol
CC and the polyketide moiety (Probable). The short-chain
CC dehydrogenase/reductase eupG and the flavin-dependent monooxygenase
CC eupH are also essential for eupenifeldin biosynthesis and are likely
CC the additional decorating enzymes of the tropolone-humulene skeleton to
CC produce final eupenifeldin or derivatives (Probable).
CC {ECO:0000269|PubMed:30980906, ECO:0000305|PubMed:30980906}.
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|PubMed:30980906}.
CC -!- DISRUPTION PHENOTYPE: Abolishes the production of eupenifeldin.
CC {ECO:0000269|PubMed:30980906}.
CC -!- BIOTECHNOLOGY: Eupenifeldin is a bistropolone-humulene meroterpenoid
CC first discovered as an antitumor and anti-leukemia agent
CC (PubMed:8360103). This metabolite shows also anthelmintic activity
CC against the parasitic worm Hemonchus contortus, anti-malarial activity
CC as well as antifungal activity (PubMed:18095654, Ref.4).
CC {ECO:0000269|PubMed:18095654, ECO:0000269|PubMed:8360103,
CC ECO:0000269|Ref.4}.
CC -!- SIMILARITY: Belongs to the short-chain dehydrogenases/reductases (SDR)
CC family. {ECO:0000305}.
