本明細書は、細菌バイオフィルムの主要なタンパク質性構成要素を遺伝的に修飾して機能性ペプチドを提示するようにすることにより、幅広い有益な応用、限定されるものではないが例えば産業用生体触媒作用、バイオレメディエーション、バイオエネルギー、物質のテンプレーティング、及びバイオセンシングのためにバイオフィルムをリプログラミングする方法を説明する。この技術は、分泌されたタンパク質の自己組織化により形成される細胞表面に固定されたアミロイド細線維からなるE.coliのcurliシステムに基づく(図1A〜1F)。本明細書に記載の技術は、機能性ペプチドドメインを分泌タンパク質に付加することにより、これが組織化された後、アミロイド細線維ネットワークが機能(例えば、種々の生物学的及び化学的実体への結合)の増大を示すようにすることができることを示している。更に、この細胞外マトリックス−ペプチド提示技術は任意のタンパク質の固定化に適応させることができる。
・ペプチド/固定化タンパク質自体に由来する又はテンプレーティングされる材料の誘導に由来する、プログラム可能な光学的特性、磁気抵抗特性、又は半導体の特性を有する、生物学的に生成されたナノ材料。
・curliバイオフィルム上に触媒ペプチド又は酵素を提示することにより、バイオフィルムの接着に種々の固定化基質を用いることができ、任意のバイオリアクターデザインで用いることができる、高効率な固定化された生体触媒作用のためのシステムが考えられる。
・ペプチド/固定化タンパク質は、バイオフィルムが組織スキャフォールド又はワクチン送達材料として働くことを可能にする生物学的に活性な生体分子をコードしてもよい。
・合成ホルモン、小分子、又は有害金属等の環境毒素に結合する又はこれを酵素的に中和するペプチド/固定化タンパク質の発現を、バイオレメディエーションのためのバイオフィルムに基づく技術として用いることができる。
・本明細書に記載されているバイオフィルム上に金、銀、白金、及びロジウム等の貴金属に特異的に結合できるペプチドを発現させることにより、そのような貴重な物質を高い収益性で回収するための非常に広い活性表面積が得られ得る。
・curliナノファイバーは、本来的に伝導性であるペプチド/タンパク質の提示により、又は伝導性である材料のテンプレーティング/固定により、多くの先端材料用途のための伝導性ナノワイヤーとして改変することができる。
・FePO4等の伝導性又は半伝導性材料のテンプレートとなることができるペプチドのcurliバイオフィルム上での発現に基づくエネルギー貯蔵のためのナノワイヤーを作製するための細菌の使用。
・提示ペプチドを介して鋼、ガラス、又は金等の特異的基質に強く結合するように細菌を特異的に改変することができる。そのような物質特異的結合は、バイオフィルムに基づくバイオセンシング技術の基礎を形成することができる。
・curliナノファイバーマトリックスは、別の物質の機械的特性を強化する又は変化させるために、他の分子と相互作用するペプチド/タンパク質を提示するように改変することもできる。
・curliを特異的物質に接着するように改変することにより、バイオフィルムは、適応及び再生に関する利点、例えば幅広い固定化基質上での生体触媒作用、物質に対する腐食耐性、微生物燃料電池用途でのバイオフィルム被覆度の増大、を提供できる生きたコーティングとして働くことができ、又は環境応答性有機(バイオフィルム)−無機(基質)材料として働くことができる。

CsgAのC末端に融合させることができる機能性ドメインのモジュール性を調べるために、本発明者らは、C3の6アミノ酸可変リンカーを維持しつつ、サイズが7〜59アミノ酸のペプチドドメイン融合体のライブラリーを作成した(表1)。ライブラリーは更に種々の二次構造を表し、ほとんどのペプチドは決まったコンフォメーションを示すようにデザインされていないが、MBD及びMms635は細胞内ジスルフィド結合を含み、これによって、より強固なコンフォメーションにロックされると考えられる。最後に、タンパク質の捕捉36並びに無機ナノ粒子37〜39及び表面33への結合を含む種々の技術へのBINDシステムの将来の応用に有用であり得る種々の機能にまたがるようにライブラリーのメンバーをデザインした。ライブラリーメンバーをLSR10細胞にクローニングし、CR染色によりcurliに基づくアミロイドネットワークの形成について調べた。ほとんどのライブラリーメンバーの陽性CR染色(図2A)及び定量分析(図4)は、小さなペプチド融合体がcurli搬出機構に許容され、細胞外アミロイドネットワークへの組織化に成功することを示唆している。陽性の染色がなかった唯一の変異体は59アミノ酸Mms6ドメインであった。CsgAは折り畳まれていない配座異性体としてCsgG複合体により外膜を横切って輸送される15と考えられているので、このことは全く予想されないわけではなかった。CsgG複合体のポアサイズが約2nmと推定されている24ことを考えると、このことは、より大きな折り畳まれたドメインはcurli搬出機構と適合しないかも知れないことを示唆している。
