Description
一般に、PPKは、ATPおよび無機ポリリン酸の可逆的形成を触媒する:
さらに、この無細胞培養装置(21)は、好気性ならびに嫌気性生物の増殖に適応するように構成され得る。さらに、無細胞発現バイオリアクター(22)および無細胞培養装置(21)の両方は、微細藻類、植物細胞、などの種々の細胞培養物に適応し得る。
実施例1:G.ステアロサーモフィルスからの耐熱性Gst RNAPの生成。
この好ましい実施形態では、本発明者らは、G.ステアロサーモフィルス由来のRNAポリメラーゼ(Gst RNAP)が、G.ステアロサーモフィルスから単離したゲノムDNA(gDNA)からクローニングされ得ることを示した。この実施形態では、約20mlのG.ステアロサーモフィルスを一晩の培養で増殖させ、その後、例えば、遠心分離機でペレット化した。その後、この例では、Macherey-Nagel NuceloSpin Microbial DNA Kitなどの市販のgDNA精製キットを用いてgDNAを単離した。その後、gDNAは、エタノール沈殿を用いて濃縮され得る。これは通常、塩およびエタノールをgDNA含有溶液に加えてgDNAを沈殿させ、これを、例えば、遠心分離機で再度ペレット化した後、DNアーゼ/RNアーゼ不含水に再懸濁させることにより、達成され得る。
-4mMの各リボヌクレアーゼ三リン酸(rNTP);
-250ng DNA;
-2μl Gst RNAP;
-20U RNアーゼ阻害剤;および
-5μl 5x反応緩衝液
本発明者らは、Gst AdkおよびTaqPPKの単離と精製を示し、この精製タンパク質を以下に記載のその後のアッセイに利用した。具体的には、本明細書で概略記載の方法を用いて、Gst AdkおよびTaqPPKが発現および単離された。図7を参照すると、精製された組換えタンパク質が4~20%SDS PAGEで分析された。ゲルは、クマシー染料で染色された。
本発明者らは、商業的に入手できるATP測定アッセイにより、本発明のAdK/PPKの組み合わせによるATP再生能力を実証した。ここでは、本発明者らは、Life TechnologiesのD-ルシフェリン、A22066を用いて、Gst Adkおよび/またはPPKタンパク質(この実施形態では、大腸菌由来)のATP再生における機能を実証した。
i)10μM ATP
ii)5μl Gst Adk
iii)5μlの大腸菌由来PPK(例示のみ)
iv)50μl ポリリン酸(1mg/ml ストック溶液)
本発明者らは、商業的に入手できるATP測定アッセイにより、本発明のGst Adk/TaqPPKの組み合わせによるエネルギー再生が種々のポリリン酸濃度で達成され得ることを実証した。具体的には、添加するPPiの量の標準反応設定を種々変更した。ルシフェラーゼシグナル(RLU)を経時的に(分)測定した。
本発明者らは、Gst Adk/TaqPPK系が、発生源としてのPPiおよびAMPなどの安価な材料からエネルギー(ATP)を生成できることを実証した。この新規ATP再生系をさらに確証するために、本発明者らは、ルシフェラーゼアッセイからGst Adk/TaqPPKの反応を分離した。具体的には、本発明者らは、最初に、精製されたGst AdkおよびTaqPPK ATPタンパク質を用いて、AMP/PPiからATPを生成し、反応物を精製し、試料を使用してルシフェラーゼアッセイを実施した-これは、上記のように、発光するためにATPを必要とする。
本発明者らは、AMPおよびPPiからのATPエネルギーの生成、およびGst Adk/TaqPPKエネルギー再生系の少なくとも1つの一実施形態によるATPの生成を実証した。具体的には、本発明者らは、通常必要なATPをAMPで置換し、エネルギー再生系成分、すなわち、Gst Adk、TaqPPK、およびPPiを加えた、ルシフェラーゼアッセイを実施した。対照実験では、本発明者らは、それぞれの成分およびこれらの組み合わせを除外した。
遺伝子改変生物不含(GMO-free)、精製大豆ペプトンおよび動物起源物質不含(ASM-free)カゼイントリプトンベースの、明確で、非毒性、非有害な培地が、遺伝子改変ゲオバチルス株の発酵のために本発明者らにより開発された。この培地は、遺伝子改変ゲオバチルス株の生産的発酵のための、潜在的に毒性の金属塩類または金属イオンキレート化剤(例えば、トリニトリル酢酸、など)の添加を必要としない。発酵温度範囲は、約52~55℃に設定され、安定に保持され得るが、より大きな温度範囲も意図されており、使用可能である。培養は、pH約7.2~7.6に維持され得るが、より広いpH範囲も意図されており、使用可能である。10mMのヘペス緩衝液の添加は、必要に応じて行われ得る。非毒性のシリコーン系消泡剤は、制御された発酵プロセスのために、必要に応じ添加され得る。
上述のように、本発明者らは、σ因子RpoD(ゲオバチルス由来)の過剰発現が大腸菌およびゲオバチルスの細菌培養物中の細菌性RNAポリメラーゼ(RNAP)を発現上昇させたことを観察した。組み換え遺伝子構築物は、ゲオバチルス中で構成的に遺伝子改変バージョンのRpoDxを発現するように調製された。遺伝子構築物の機能的信頼性およびタンパク質発現レベルが測定され、同じゲオバチルス株中に形質転換されたsfGFP構築物を用いて、作製した溶解物の510nmの蛍光読み値により、モニターされる。
上記で詳述のように、特定の実施形態では、本発明は、細胞エネルギー源、ATPが、二重酵素系を用いて無機ポリリン酸から再生される無細胞発現系に関する。大腸菌からクローニングされ、産生されたホモログ酵素(ecPPKまたはPPK)に対して、ポリリン酸加水分解活性が観察された後で、サーモフィルス・アクアティクス由来の耐熱性のポリリン酸キナーゼ(PPK)(TaqPPK)を利用して、系のための1つの酵素が開発された。報告されたPPK活性の他に、コレラ菌から単離されたTaqPPKおよびecPPKは、AMPからADPを生成し、加水分解された無機ポリリン酸(iPPi)を生成するのが好ましい。第2の酵素ステップとして、その後、2分子のADPが、耐熱性のアデノシンキナーゼ(AdK)により再構成されて、1つのユニットのATPおよびAMPを形成する。
一実施形態では、CF系は、トリス酢酸緩衝液(CF-1)を用いて、供給および反応コンパートメント中でpH6.9~8.0の範囲で調節および安定化され得る。反応容器中の溶解物の最終濃度は、100~110mg/ml総タンパク質であり得、一方、テンプレートDNA(あるいは、プレランRNA/RNAP反応として一緒に)は、補助因子、アミノ酸およびヌクレオチドと一緒に溶解物に添加される。供給溶液は、同一濃度のヌクレオチドおよび全天然アミノ酸を含む。補助因子、ソルビトールおよび上述の酵素も同様に添加される。材料の詳細リストは、夏季に適用され、通常、無細胞反応成分と呼ばれ得る。さらに、二重酵素ATP再生系の一般的成分を含め得る。好ましい一実施形態では、このような成分は、限定されないが、一定量のGst Adk、一定量のTaqPPK、および/または一定量のPPi、および/または一定量のAMPを含み得る。追加の実施形態は、一定量のGst SDHおよびソルビトールを含み得る。
