Catalytically Active Silica Nanoparticle-Based Supramolecular Architectures of Two Proteins - Cellobiose Dehydrogenase and Cytochrome c on Electrodes
(2012) In Langmuir 28(25). p.9189-9194- Abstract
- Artificial nanobiomolecular architectures that follow natural examples in protein assembly become more and more important from basic and applied points of view. Our study describes the investigation on cellobiose dehydrogenase (CDH), cytochrome c (cyt c), and silica nanoparticles (SiNP's) for the construction of fully catalytically active supramolecular architectures on electrodes. We report on intraprotein, interprotein, and direct electron-transfer reaction cascades of cellobiose dehydrogenase and cytochrome c immobilized in multiple supramolecular layers. Carboxy-modified SiNP's are used to provide an artificial matrix, which enables protein arrangement in an electroactive form. Direct and interprotein electron transfer has been... (More)

Carboxy-modified SiNP's are used to provide an artificial matrix, which enables protein arrangement in an electroactive form. Direct and interprotein electron transfer has been established for a two-protein system with CDH and cyt c in a layered architecture for the first time. We also highlight that the glycosylation of CDH and the silica nanoparticle size play key roles in the mode of operation in such a complex system. The response of the specific substrate, here lactose, can be tuned by the number of immobilized nanobiomolecular layers. (Less)
