酶固定化是增强酶的稳定性和可回收性并促进酶从反应产物中分离的重要策略。然而,酶纯化后进行单独的化学步骤以固定在固体支持物上会降低活性酶的效率和产量。在这里,我们描述了自发组装成纳米原纤维的多肽构建体,其融合的活性酶亚基展示在淀粉样蛋白原纤维表面上。我们测量了原纤维内附加酶的稳态动力学参数,并将其与溶液中相同的蛋白质构建体进行了比较。最后,我们证明了原纤维可以在传统批量过程和连续流微反应器中回收并重新用于功能测定。
Enzyme immobilization is an important strategy to enhance the stability and recoverability of enzymes and to facilitate the separation of enzymes from reaction products. However, enzyme purification followed by separate chemical steps to allow immobilization on a solid support reduces the efficiency and yield of the active enzyme. Here we describe polypeptide constructs that self-assemble spontaneously into nanofibrils with fused active enzyme subunits displayed on the amyloid fibril surface. We measured the steady-state kinetic parameters for the appended enzymes in situ within fibrils and compare these with the identical protein constructs in solution. Finally, we demonstrated that the fibrils can be recycled and reused in functional assays both in conventional batch processes and in a continuous-flow microreactor.
