Abstract

[FeFe]-hydrogenases are highly-active hydrogen-conversion biocatalysts using Earth-abundant metals in their active-site. Understanding their mechanism may enable design of catalysts for renewable energy storage. Here, observation of the crucial Fe-hydride-containing (Hhyd) intermediate in a PDT-variant of [FeFe]-hydrogenase reveals deeper insight into the role of the dithiolate bridgehead in the catalytic mechanism.

[FeFe]氢化酶末端氢化物形成:了解二硫酸酯桥头堡的作用
[FeFe]-氢化酶是一种高活性的氢转化生物催化剂,其活性位点使用地球上丰富的金属。了解它们的机理可能有助于设计用于可再生能源储存的催化剂。在这里,对[FeFe]-氢化酶pdt变体中关键的含铁氢化物(Hhyd)中间体的观察揭示了对二硫酸桥头堡在催化机制中的作用的更深入的了解。
