Description
以下、実施例を挙げて本発明をより詳しく説明する。これらの実施例は、単に本発明を例示するためのもので、本発明の範囲がこれら実施例により限定されると解釈されてはならない。
本実施例ではトリプトファン生産能を有する菌株でホスファターゼ活性が不活性化された菌株を製作しようとした。
本実施例ではトリプトファンを生産するもう一つの代表的な大腸菌であるKCCM11166P(特許文献5)を親菌株とし、ホスファターゼをコードするものと推定されるyigL遺伝子を前記実施例1記述した方法と同様に相同組換えにより欠失させた。
前記実施例1で製造したW3110 trpΔ2 yigLと親菌株であるW3110 trpΔ2のトリプトファン生成能を比較するためにそれぞれの菌株にpCL−Dtrp_att−trpEDCBAとpBAC−Dtrp_att−trpDCBAを形質転換方法により導入した。導入されたベクターはトリプトファンオペロン調節部位の調節機序が解除され、トリプトファンを過量生産することができるようにトリプトファンオペロン発現が強化されたベクターである(特許文献3)。ベクターが導入された菌株は下記表2の組成のとおりに製造されたトリプトファン評価培地で培養してL−トリプトファン生産能を比較した。
前記実施例2で製造したyigL欠損株(CA04-2803)と親菌株であるKCCM11166Pとのトリプトファン力価を測定するために、下記表4の組成のとおりに製造されたトリプトファン力価培地で培養してL−トリプトファン生産効率の向上を確認した。
受託番号:KCCM11635P
受託日付:2014年12月05日
Claims (1)
- (i)配列番号1のアミノ酸配列を含むホスファターゼ(phosphatase)の活性が不活性化されるように変異されたエシェリキア属微生物を培地で培養する段階;及び
(ii)前記培養による培地または前記微生物からL−トリプトファンを回収する段階を含む、L−トリプトファンの製造方法。
