Abstract

Enzymatic reductions catalyzed by reductases generally depend on reduced nicotinamide cofactors as a hydride source. However, for industrial viability, it is more cost-effective to use water as the hydrogen source, bypassing the requirement for the cofactor. Here we report a hybrid photo-biocatalyst system based on infrared (IR) light and responsive reductive graphene quantum dots (rGQDs), for performing the direct transfer of hydrogen from water to prochiral substrates. The photo-biocatalyst, assembled from rGQDs and cross-linked aldo-keto reductase (AKR), mediates the synthesis of the pharmaceutical intermediate, (R)-1-[3,5-bis(trifluoromethyl)-phenyl] ethanol ((R)-3,5-BTPE), in 82% yield and >99.99% ee under IR illumination. Our photo-enzymatic systems can also be effectively used to drive the enzymatic reduction of imines and alkenes. Since the hybrid photo-biocatalysts are insoluble, they can be readily recovered and recycled. This work opens new avenues to create artificial photo-biocatalyst systems, enabling the facile coupling of renewable solar energy and sustainable chemical production.

还原性石墨烯量子点介导的与水无关的光酶还原。

由还原酶催化的酶还原通常依赖于还原的烟酰胺辅助因子作为氢化物来源。然而，为了工业可行性，使用水作为氢源更具有成本效益，绕过了对辅因子的要求。本文报道了一种基于红外（IR）光和响应性还原性石墨烯量子点（rGQDs）的混合光生物催化剂系统，用于将氢从水中直接转移到前手性底物。该光生物催化剂由rGQDs和交联醛酮还原酶（AKR）组装而成，在红外光照下催化合成医药中间体(R)-1-[3,5-双（三氟甲基）苯基]乙醇（(R)-3,5- btpe），产率为82%，ee为99.99%。我们的光酶系统也可以有效地用于驱动亚胺和烯烃的酶还原。由于混合光生物催化剂是不溶的，它们可以很容易地回收和循环利用。这项工作为创建人工光生物催化剂系统开辟了新的途径，使可再生太阳能和可持续化学生产能够轻松耦合。
