既存の形質転換手法を置き換えるほどのメリットは無さそうだけど、この技術を元に何かは出来そう。
細菌に出来事の数え方を教えるお話
Advent Calender「今年読んだ一番好きな論文2020」の記事です。
3行で紹介
2020年9月にNature Communicationsに出たこちらの論文を紹介します。
細菌の群れが出来事の種類と回数を記憶出来る仕組みを、人工的に効率よく作れるようにしましたというお話です。出来事の種類と回数に応じてDNAが書き換えられるようなシステムを構築し、遺伝子から発現する蛍光タンパク質の色を変えています。
生物の仕組みをつくる研究の流れ
今回の紹介論文は、仕組みをつくる流れの研究の一つで、細菌の遺伝情報の中に論理演算の仕組みを組み込んで、ヒトがデザインした通りに出来事を数えさせようというものです。
数を数えさせる仕組み
細菌に数を数えさせる仕組みの鍵となるのは、インテグラーゼ(integrase)と呼ばれる酵素です。この酵素は、DNA上の2種類のマーカー配列(attB, attP)を認識して、そのマーカーの方向によってDNAに2つの異なった作用を不可逆的に施します。
- マーカーが向き合っている場合: 間のDNAを反転させる(画像左側の反応)
- マーカーが同一方向の場合: 間のDNAを切り取る(画像右側の反応)
このようなインテグラーゼを2種類組み合わせると、aとbの2種類の出来事(薬剤等による刺激)の順番によって別々の挙動を示す回路が出来上がります。下図の太い矢印(0, 1, 2)はそれぞれの色の蛍光タンパク質がコードされた遺伝子を表していて、遺伝子は方向性をもつため特定の方向でコードされている場合のみ正常にはたらきます。下図の曲がった矢印は、プロモーターと呼ばれるDNA領域で、遺伝子が読み取られる方向を決定しています。なお、プロモーター自体は左右どちらの方向であっても正常に機能することが出来ます。出来事が起こる前(0の状態)では、青色のタンパク質が発現していて、出来事の種類によって2種類のインテグラーゼのどちらかがはたらき、先に述べたDNAの反転または切り出しが起こります。
- 出来事b(右側、オレンジ色の矢印)が起こった場合
オレンジ色のマーカーにインテグラーゼが働き、マーカーは同一方向のためDNAが切り出されます。正しい方向の蛍光タンパク質もまだ使われていない水色のマーカーも無くなってしまいます。
- 出来事a(左側、水色の矢印)が起こった場合
水色のマーカーにインテグラーゼがはたらき、マーカーが向き合っているのでDNAが反転します。結果として、青色のタンパク質は方向が逆になってしまって機能を失い、代わりに正しい方向になった赤色のタンパク質が発現します。また、オレンジ色のマーカーが向き合うため、引き続いて出来事bが起こると、オレンジ色のマーカーの間でDNAの反転が起こり、プロモーターが逆向きになります。これによって遺伝子の読み取り方向がプロモーターから左側に進ようになるため、緑色のタンパク質が代わりに発現するようになります。
このようにして、細菌が出来事の数と順番を数え、それに応じて異なる遺伝子を発現させる仕組みが出来上がりました。ちなみに、ここまでの研究は2013年に発表されたもの*5の追試です。
より複雑な出来事の数え方
前節までの話は、すでに先行研究で発表されていた内容でした。紹介論文では、細菌がより複雑な出来事も正確に数えられるように仕組みを発展させ、また、出来事の順番を好きなように入れ替えても上手くはたらくようにデザインの効率化を行いました。
その1: 複数の細菌株に分ける
複雑化のその1では、それまで一種類の細菌株で行なっていた演算を複数の株に分けるシステムを実装しました。このシステムの主目的は、演算がより複雑になった場合に、一つの細菌では演算が処理仕切れなくなってしまう事態(具体的には、遺伝子の発現量の限界や導入する遺伝子の合計サイズの限界)を防ぐ事や、出力部分でより複雑な反応をさせたい場合に、反応同士が混み合ってしまう事態を防ぐ事などにあります。
拡張したシステムの生物学的な実装の方法としては、一種類の細菌が保持していた遺伝子を複数の細菌に分けてあげました。例として下図3cを見てみると、青色と緑色蛍光タンパク質の部分を2SP8株に、赤色蛍光タンパク質の部分を2SP5株に分配しています。
その2: 数えられる出来事の種類を増やす
複雑化のその2では、数えられる出来事の種類を増やして演算の自由度を上げました。これによって、現実的に演算を複雑化させる事が可能になります。
以下の図4cには、3種類の出来事を数えられる細菌の例が示されています。この例では、出来事がc→b→aの順番で起こった場合のみ蛍光タンパク質の色の変化が見られます。
複雑な系の実装
複雑化のその1とその2を組み合わせて出来たシステムの様子と結果(棒グラフ)が以下の図6に示されています。aに示されている細菌株の組み合わせによって、出来事の数え方が異なっている様子がbとcとで比較されています。
まとめ
仕組みの実装をするという事を結構簡単に書いてしまいましたが、実際の実験では予期しないところで蛍光タンパク質が発現してしまったり(図6cでは少し残っている)、発現しているはずの蛍光タンパク質が見られなかったりする事が多々(多々)あるので、結構泥臭い最適化が必要だったりします。省略しましたが図で示されている回路のデザインは筆者らが主張する効率の良い最適化スキームで作られていて、この仕組みを応用に使う研究者や企業が他のインテグラーゼや細菌で検証を行う事が期待されます。
