Yuki Kitazumi 교수의 연구실은 생체전기화학 분야에서 활동하며, 특히 효소 기반의 직접 전자 이송(Direct Electron Transfer, DET) 메커니즘을 중심으로 한 생체 전기화학 촉매 연구에 집중하고 있습니다. 고도로 제어된 나노구조 전극 설계와 단백질 공학을 통해 효소의 전기화학적 성능을 극대화하는 데 초점을 맞추고 있으며, 특히 막에 통합된 알데하이드 탈수소효소의 전기화학적 반응 기작과 반응 방향 제어에 대한 기초 연구를 진행하고 있습니다. 이는 에너지 변환 및 생체 센서 응용에 기여할 잠재력을 지닌 학문적 기초 연구입니다.

Direct electron transfer (DET)-type bioelectrocatalysis, which couples the electrode reactions and catalytic functions of redox enzymes without any redox mediator, is one of the most intriguing subjects that has been studied over the past few decades in the field of bioelectrochemistry. In order to realize the DET-type bioelectrocatalysis and improve the performance, nanostructures of the electrode surface have to be carefully tuned for each enzyme. In addition, enzymes can also be tuned by the
The adsorption of decylsulfate (DeSO4(-)) and decylammonium (DeNH(3+)) at the 1,2-dichloroethane (DCE)|water(W) interface has been examined as a function of the phase-boundary potential by simultaneous recording of electrocapillary curves and voltammograms. The standard Gibbs energies for the adsorption of DeSO(4)(-) and DeNH(3)(+) at the DCE|W interface from the W phase depend linearly on the phase-boundary potential, having the slopes of 9.1 and-9.8 kJ mol-1 V-1, respectively. These values sug
The bioelectrocatalytic properties of membrane-bound aldehyde dehydrogenase (AlDH) from Gluconobacter oxydans NBRC12528 were evaluated. AlDH exhibited direct electron transfer (DET)-type bioelectrocatalytic activity for acetaldehyde oxidation at several kinds of electrodes. The kinetic and thermodynamic parameters for bioelectrocatalytic acetaldehyde oxidation were estimated based on the partially random orientation model. Moreover, at the multi-walled carbon nanotube-modified electrode, the coo
