[実施例1:一般的方法、菌株及びプラスミド]
別段の記載がない限り、全ての培地及び一般的方法は、国際公開第2017036903号パンフレットに開示されている。使用される枯草菌(B.subtilis)の菌株の遺伝子型(Genotyps)は表1に挙げられている。
アルファルファ根粒菌(S.meliloti)のIFO14782株のpdxP遺伝子(配列番号1)を、PCRにより、プライマーP1(配列番号5)及びP2(配列番号6)を使用して増幅させた。これらのオリゴは、BamHI(GGATTC)制限部位及びNheI(GCTAGC)制限部位をそれぞれもつ。得られた0.8kbの断片をアガロースゲル電気泳動により精製し、QIAquick Gel Extraction Kit(キアゲン)を使用してゲルから抽出した。精製したPCR産物を、国際公開第2008000632号パンフレットに記載されているpBHA12大腸菌(E.coli)/枯草菌(B.subtilis)シャトルベクターの多重クローニング部位のBamHI及びNheIでクローン化した。このベクターは、バチルス・アミロリケファシエンス(Bacillus amyloliquefaciens)のamyQ遺伝子に由来するプロモーターの制御下で、pdxP遺伝子の発現を可能にする。クローニング及び枯草菌(B.subtilis)の形質転換の手順において、大腸菌(E.coli)を中間宿主として使用した。ライゲーション混合物の形質転換を、最初にTOP10 Chemically Competent E.coli(Invitrogen)で行った。大腸菌(E.coli)のアンピシリン耐性コロニーを幾つか単離し、組換えプラスミドpBV213L(図1を参照)を、QIAprep Spin Miniprep Kit(キアゲン)を使用して抽出した。枯草菌(Bacillus subtilis)のBS168-SP1株は、Marburg168株(ドイツ)のトリプトファン原栄養性誘導体であり、trpC2変異を、枯草菌(B.subtilis)ATCC6051株に由来する非変異のtrpC遺伝子で置換することによって作製した。BS168-SP1の構築は、国際公開第2017036903号パンフレットに詳細に記載されている。BS168-SP1は、リボフラビンの過剰産生に関してはナイーブな株である。次のステップでは、10μlのプラスミドpBHA12(国際公開第2008000632号パンフレット)又は10μlのプラスミドpBV213Lで、BS168-SP1株を、コンピテント細胞形質転換により形質転換し、TBABプレート上でカナマイシン耐性クローンを選択した(10μg/ml f.c.)。得られたBS9645株及びBS9646株は、空ベクターpBHA12(BS9645)又はアルファルファ根粒菌(S.meliloti)のpdxP遺伝子(BS9646)を含む組換えベクターpBV213Lをそれぞれもっていることを確認した。コード配列の開始コドンを示すヌクレオチド配列が、表2に、配列表の配列番号に対応して記載されている。
コドン最適化したpdxP遺伝子(配列番号4)-非改変の遺伝子と同じタンパク質をコードする-を、BS168-SP1レシピエント株の染色体中のamyE遺伝子座に挿入した。オーバーハングエクステンションによるスプライシング(splicing by overhang extension:SOEing)PCRを使用して、amyE-5’DNA配列及びamyE-3’DNA配列が隣接する、pdxP*遺伝子を担持するDNA断片を生成した。これは二重交差によってBS168-SP1染色体中に安定な挿入を可能にする。クロラムフェニコールアセチルトランスフェラーゼ(E.C2.3.1.28)遺伝子をもつ遺伝子モジュール(クロラムフェニコールに対する抗生物質耐性になってくれる)も、amy-E3’隣接領域とpdxP*遺伝子との間に、pdxP*とは逆向きに挿入した。最初に、個別のPCRを実行して、(i)pDG1662プラスミド(Bacillus Genetic Stock Center,オハイオ州立大学(The Ohio State University),米国;GenBank U46197)からの、amyE-3’隣接領域及びクロラムフェニコールカセットを担持する1.9kbのDNA領域を、プライマー対P3(配列番号7)及びP4(配列番号8)を使用して増幅し;(ii)pdxP*遺伝子を担持する0.9kbのDNA領域を、プライマー対P5(配列番号9)及びP6(配列番号10)を使用して増幅した。アルファルファ根粒菌(S.meliloti)のIFO14782 pdxP*コード配列(配列番号4)(その発現は、枯草菌(B.subtilis)vegプロモーター及び枯草菌(B.subtilis)spoVG RBS(配列番号3)によって引き起こされる)を、ジェンスクリプト、ピスカタウェイ、ニュージャージー(Genscript,Piscataway,NJ)、米国が合成し、ベクターpJET1.2(サーモフィッシャーサイエンティフィック(Thermo Fisher Scientific))の中にクローン化した。この組換えベクターをPCRのためのテンプレートとして使用し、(iii)pDG1662プラスミドからのamyE-5’隣接領域を担持する0.5kbのDNA領域を、プライマー対P7(配列番号11)及びP8(配列番号12)を使用して増幅した。3つのPCR産物を、アガロースゲル電気泳動により分離し、QIAquick Gel Extraction Kit(キアゲン)を使用してゲルから抽出した。重複DNA領域があるため、プライマー対P3及びP8を使用すると、これらは3.2kbのSOEing PCR断片中に集合した。得られたSOEing PCR産物をアガロースゲル電気泳動により精製し、QIAquick Gel Extraction Kit(キアゲン)を使用してゲルから抽出した。次いで、コンピテント枯草菌(B.subtilis)BS168-SP1の形質転換のために1μgを使用した。クロラムフェニコール耐性(CmR)コロニーを、クロラムフェニコール5μg/mlを含有するTBABプレート上で選択した。BS168-SP1の染色体のamyE遺伝子(アルファアミラーゼ)の中へのpdxP*の挿入を、デンプン加水分解試験により、ヨード染色法を使用して確認した。得られたBS9502株の正確な遺伝子型もPCRにより確認した。次いで、枯草菌(B.subtilis)のリボフラビンを過剰産生するBS4905株(国際公開第2017036903号パンフレットに記載されている)の染色体のamyE遺伝子座の中へのpdxP*遺伝子の挿入を、上記の方法に従ってSPP1ファージを用いて実行し、BS9502のライセートを使用して、枯草菌(B.subtilis)のBS4905株に形質導入した。CmRコロニーを、クロラムフェニコール5μg/mlを含有するTBABプレート上で選択した。BS168-SP1の染色体のamyE遺伝子(アルファアミラーゼ)の中へのpdxP*の挿入を、デンプン加水分解試験により、ヨード染色法を使用して確認した。得られたBS8638株の正確な遺伝子型もPCRにより確認した。
pdxP遺伝子は、BS9646株の中の複製ベクターに(実施例2を参照)、及びBS8638株の中への染色体の挿入により(実施例3を参照)、過剰発現する。リボフラビン産生のアッセイを、上記のように、ディープウェルマイクロタイタープレート中、RSMでの培養物から行った。結果を表3に示す。
アルファルファ根粒菌(S.meliloti)のPdxPを使用してホモロジー検索をすると、他のリゾビウム属(Rhizobium)の菌株から幾つかのpdxPホモログが明らかになった(表4を参照)。
