第一の態様において本発明は、ペデリン生合成遺伝子クラスターを含むか、またはペデリン生合成遺伝子クラスターを含む配列と相補性の分離された核酸を提供する。このクラスターは、薬物候補物質の生合成物をコードする培養に適さない共生体由来の遺伝子の第一の例になる。
分離された核酸は図3により詳細に示すように、好ましくはこのペデリン生合成遺伝子クラスターの個々の単位および/またはモジュールを形成する核酸断片を含む。図3に示すこのクラスターは、個々の酵素または1もしくは数個のポリケチドシンターゼの解読単位か、あるいは非リボソームペプチドシンテターゼのモジュールのいずれかである単位pedA〜pedHを含有する。例えばpedF単位は5個のポリケチドシンターゼのモジュールと1個のペプチドシンテターゼのモジュールを含み、および/またはpedH単位は4個のポリケチドシンターゼのモジュールと1個のペプチドシンテターゼのモジュールを含む。各ポリケチドシンターゼのモジュールは、少なくとも1個のケトシンターゼドメインと1個のアシル担体タンパク質ドメインを含む。この分離された核酸は好ましくは、本質的にSEQ ID NO:2〜9の示すタンパク質配列をコードする核酸配列からなる1または複数個のpedA〜pedH単位を含む。
a)SEQ ID NO:1の示すヌクレオチド配列、または
b)SEQ ID NO:1の補体であるヌクレオチド配列、または
c)高度緊縮条件下でSEQ ID NO:1ともしくはその補体とハイブリッドを形成するヌクレオチド配列、または

次に本発明を、ある特定の実施例に関してさらに詳細に述べることにする。
ペデリンの分析:甲虫の種は、R. L. L. KellnerおよびH. Baspinarの方法により決定した。甲虫は、DNAを保護するために採集後直ちに別々にエタノール中で保管した。ペデリンの分析の場合、このエタノールを50μLまで濃縮し、10μLをシリカゲルTLCプレート(Merck社)上に点滴した。次いでプレートを酢酸エチル中で展開し、アニスアルデヒド試薬で染色した。RF = 0.22におけるピンクの点がペデリンに特異的であった。
