CC -!- FUNCTION: Alcohol dehydrogenase; part of the gene cluster that mediates
CC the biosynthesis of notoamide, a fungal indole alkaloid that belongs to
CC a family of natural products containing a characteristic
CC bicyclo[2.2.2]diazaoctane core (PubMed:20722388). The first step of
CC notoamide biosynthesis involves coupling of L-proline and L-tryptophan
CC by the bimodular NRPS notE, to produce cyclo-L-tryptophan-L-proline
CC called brevianamide F (PubMed:20722388). The reverse prenyltransferase
CC notF then acts as a deoxybrevianamide E synthase and converts
CC brevianamide F to deoxybrevianamide E via reverse prenylation at C-2 of
CC the indole ring leading to the bicyclo[2.2.2]diazaoctane core
CC (PubMed:20722388). Deoxybrevianamide E is further hydroxylated at C-6
CC of the indole ring, likely catalyzed by the cytochrome P450
CC monooxygenase notG, to yield 6-hydroxy-deoxybrevianamide E (Probable).
CC 6-hydroxy-deoxybrevianamide E is a specific substrate of the
CC prenyltransferase notC for normal prenylation at C-7 to produce 6-
CC hydroxy-7-prenyl-deoxybrevianamide, also called notoamide S
CC (PubMed:20722388). As the proposed pivotal branching point in notoamide
CC biosynthesis, notoamide S can be diverted to notoamide E through an
CC oxidative pyran ring closure putatively catalyzed by either notH
CC cytochrome P450 monooxygenase or the notD FAD-linked oxidoreductase
CC (Probable). This step would be followed by an indole 2,3-epoxidation-
CC initiated pinacol-like rearrangement catalyzed by the notB FAD-
CC dependent monooxygenase leading to the formation of notoamide C and
CC notoamide D (PubMed:22188465). On the other hand notoamide S is
CC converted to notoamide T by notH (or notD), a bifunctional oxidase that
CC also functions as the intramolecular Diels-Alderase responsible for
CC generation of (+)-notoamide T (Probable). To generate antipodal (-)-
CC notoaminide T, notH' (or notD') in Aspergillus versicolor is expected
CC to catalyze a Diels-Alder reaction leading to the opposite
CC stereochemistry (Probable). The remaining oxidoreductase notD (or notH)
CC likely catalyzes the oxidative pyran ring formation to yield (+)-
CC stephacidin A (Probable). The FAD-dependent monooxygenase notI is
CC highly similar to notB and is predicted to catalyze a similar
CC conversion from (+)-stephacidin A to (-)-notoamide B via the 2,3-
CC epoxidation of (+)-stephacidin A followed by a pinacol-type
CC rearrangement (Probable). Finally, it remains unclear which enzyme
CC could be responsible for the final hydroxylation steps leading to
CC notoamide A and sclerotiamide (Probable). The fonction of notN in the
CC notoamide biosynthesis has not been determined yet (Probable).

CC -!- BIOTECHNOLOGY: Notoamides have been shown to exhibit antitumoral
CC activities (PubMed:17304611). Notoamides A-C show moderate cytotoxicity
CC against HeLa and L1210 cells with IC(50) values in the range of 22-52
CC mg/ml, but the IC(50) value of notoamide D is greater than 100 mg/ml
CC (PubMed:17304611). Moreover, notoamide C induces G2/M-cell cycle arrest
CC at a concentration of 6.3 mg/ml (PubMed:17304611).
