CC   -!- FUNCTION: Part of the gene cluster that mediates the biosynthesis of
CC       notoamide, a fungal indole alkaloid that belongs to a family of natural
CC       products containing a characteristic bicyclo[2.2.2]diazaoctane core
CC       (PubMed:23213353). The first step of notoamide biosynthesis involves
CC       coupling of L-proline and L-tryptophan by the bimodular NRPS notE', to
CC       produce cyclo-L-tryptophan-L-proline called brevianamide F (Probable).
CC       The reverse prenyltransferase notF' then acts as a deoxybrevianamide E
CC       synthase and converts brevianamide F to deoxybrevianamide E via reverse
CC       prenylation at C-2 of the indole ring leading to the
CC       bicyclo[2.2.2]diazaoctane core (PubMed:22660767) (Probable).
CC       Deoxybrevianamide E is further hydroxylated at C-6 of the indole ring,
CC       likely catalyzed by the cytochrome P450 monooxygenase notG', to yield
CC       6-hydroxy-deoxybrevianamide E (Probable). 6-hydroxy-deoxybrevianamide E
CC       is a specific substrate of the prenyltransferase notC' for normal
CC       prenylation at C-7 to produce 6-hydroxy-7-prenyl-deoxybrevianamide,
CC       also called notoamide S (Probable). As the proposed pivotal branching
CC       point in notoamide biosynthesis, notoamide S can be diverted to
CC       notoamide E through an oxidative pyran ring closure putatively
CC       catalyzed by either notH' cytochrome P450 monooxygenase or the notD'
CC       FAD-linked oxidoreductase (Probable). This step would be followed by an
CC       indole 2,3-epoxidation-initiated pinacol-like rearrangement catalyzed
CC       by the notB' FAD-dependent monooxygenase leading to the formation of
CC       notoamide C and notoamide D (Probable). On the other hand notoamide S
CC       is converted to notoamide T by notH' (or notD'), a bifunctional oxidase
CC       that also functions as the intramolecular Diels-Alderase responsible
CC       for generation of (-)-notoamide T (Probable). To generate antipodal
CC       (+)-notoaminide T, notH (or notD) in Aspergillus strain MF297-2 is
CC       expected to catalyze a Diels-Alder reaction leading to the opposite
CC       stereochemistry (Probable). The remaining oxidoreductase notD' (or
CC       notH') 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 notJ' 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).
