The biosyntheticpathway of the strained dipeptide (+)-azonazine A from marine-derived Aspergillus insulicola, which features a rarely observed benzofuranoindoline ring system, was uncovered. Heterologous reconstitution of the fourth-enzyme pathway showed a P450 enyzme catalyzes an oxidative cyclization of cyclo-(l-Trp-N-methyl-l-Tyr) to form the hexacyclic ring system. Analogs of azonazine A were
揭示了海洋来源的岛曲霉(Aspergillus insulicola)中的二肽 (+)-azonazine A 的生物合成途径,该二肽具有罕见的苯并呋喃二氢吲哚环系统。第四酶途径的异源重建表明P450酶催化环-( 1-Trp - N-甲基-1- Tyr )氧化环化形成六环系统。通过用不同的吲哚取代的色氨酸类似物补充生产菌株来产生氮嗪A的类似物。
