CC -!- FUNCTION: Cyclopenase; part of the gene cluster that mediates the
CC biosynthesis of penigequinolones, potent insecticidal alkaloids that
CC contain a highly modified 10-carbon prenyl group (PubMed:25859931). The
CC first stage is catalyzed by the nonribosomal pepdide synthetase penN
CC that condenses anthranilic acid and O-methyl-L-tyrosine to produce 4'-
CC methoxycyclopeptin (By similarity). 4'-methoxycyclopeptin is then
CC converted to 4'-methoxydehydrocyclopeptin by the ketoglutarate-
CC dependent dioxygenase penM through dehydrogenation to form a double
CC bond between C-alpha and C-beta of the O-methyltyrosine side chain (By
CC similarity). PenM also converts its first product
CC methoxydehydrocyclopeptin to 4'-methoxycyclopenin (By similarity). The
CC following conversion of 4'methoxycyclopenin into 4'-methoxyviridicatin
CC is catalyzed by the cyclopenase penL (By similarity). 4'-
CC methoxyviridicatin is the precursor of quinolone natural products, and
CC is further converted to quinolinone B (Probable). The prenyltransferase
CC penI then catalyzes the canonical Friedel-Crafts alkylation of
CC quinolinone B with dimethylallyl cation to yield dimethylallyl
CC quinolone, which is subjected to FAD-dependent dehydrogenation by the
CC FAD-linked oxidoreductase penH to yield conjugated aryl diene
CC (PubMed:25859931). The delta(3') double bond then serves as the site of
CC the second alkylation with DMAPP catalyzed by the prenyltransferase
CC penG to yield a carbenium ion intermediate, which can be attacked by
CC H(2)O to yield a styrenyl quinolone containing a C3'-hydroxyprenyl
CC chain, or undergo cyclization to yield yaequinolones J1 and J2
CC (PubMed:25859931). The conversion of the styrenyl quinolone into the
CC tetrahydrofuran-containing yaequinolone C is performed by the FAD-
CC dependent monooxygenase penE and involves epoxidation of the terminal
CC C7'-C8' olefin, followed by epoxide ring opening initiated by the C3'
CC hydroxyl group (PubMed:25859931). The predicted cysteine hydrolase penJ
CC acts as an epoxide hydrolase that enhances the rate of the 5-exo-tet
CC cyclization step, increasing the yield of yaequinolone C
CC (PubMed:25859931, PubMed:28114276). PenF catalyzes the cationic
CC rearrangement of the epoxide formed by penE (before ring opening to
CC produce yaequinolone C) into yaequinolone D (PubMed:28114276). Finally,
CC the short-chain dehydrogenase/reductase (SDR)-like reductase penD,
CC catalyzes both the dehydration of yaequinolone D and the reduction of
CC the resulting oxonium to yield penigequinolone (PubMed:28114276).
