Abstract
Electron transfer between the redox protein PQQ-GDH and carbon nanotubes, acting as a bioelectrode, has been accomplished in recent decades. In this time, the focus has been on investigating the suitability of carbon nanotubes as bioelectrodes. The reason for this lies in the biomedical applications, specifically the electron transfer between proteins and bioelectrodes, which forms the basis for the development of small medical devices. In cells, proteins are found in the cellular medium and mostly have free movement. However, to become a part of a bioelectrode, they need to be immobilized on the surface. Therefore, it is crucial to thoroughly understand the mechanism of their activity in order to influence this activity and ensure that enzymes remain active even when immobilized. The initiation of this research involves observing the electronic structure of the active site of the PQQ-GDH system before and after the electron transfer reaction occurs. The study was conducted using the Density Functional Theory (DFT) method, a Quantum Mechanical (QM) method, to determine the molecular geometry and electronic structure of the molecular system.
Abstract (croatian)
Prijenos elektrona između redoks proteina PQQ-GDH i ugljikove nanocijevi, koja djeluje kao bioelektroda, značajno je područje istraživanja je u posljednjih nekoliko desetljeća. U ovom razdoblju fokus je na ispitivanju prikladnosti ugljikovih nanocijevi kao bioelektroda. Razlog tome je biomedicinske prirode, odnosno prijenos elektrona između proteina i bioelektroda temelj je razvoja malih medicinskih uređaja. U stanicama proteini se nalaze u staničnom mediju i većinom imaju slobodno gibanje. Međutim, da bi bili dio bioelektroda, moraju biti imobilizirani na površini. Zato je bitno rauzmjeti detaljno mehanizam njihove aktivnosti, kako bi se moglo utjecati na tu aktivnost i osigurati da su enzimi aktivni i kad su imobilizirani. Začetak ovog istraživanja je na promatranju elektronske strukture aktivnog mjesta sustava proteina pirolokinolin kinon ovisna glukoza dehidrogenaza (PQQ-GDH) prije te nakon što se dogodi reakcija prijenosa elektrona. Istraživanje je odrađeno metodom teorije funkcionala gustoće (DFT), jednom od metoda kvantne mehanike, kojom je određena molekularna geometrija te elektronska struktura proučavanog molekularnog sustava.
