Alteration of Electron Acceptor Preferences in the Oxidative Half-Reaction of Flavin-Dependent Oxidases and Dehydrogenases.

Int J Mol Sci 2020 May 27;21(11). Epub 2020 May 27.

Joint Department of Biomedical Engineering, The University of North Carolina at Chapel Hill and North Carolina State University, Chapel Hill, NC 27599, USA.

In this review, recent progress in the engineering of the oxidative half-reaction of flavin-dependent oxidases and dehydrogenases is discussed, considering their current and future applications in bioelectrochemical studies, such as for the development of biosensors and biofuel cells. There have been two approaches in the studies of oxidative half-reaction: engineering of the oxidative half-reaction with oxygen, and engineering of the preference for artificial electron acceptors. The challenges for engineering oxidative half-reactions with oxygen are further categorized into the following approaches: (1) mutation to the putative residues that compose the cavity where oxygen may be located, (2) investigation of the vicinities where the reaction with oxygen may take place, and (3) investigation of possible oxygen access routes to the isoalloxazine ring.

Correlation between the loss of intracellular molecules and cell viability after cell electroporation.

Bioelectrochemistry 2020 May 13;135:107550. Epub 2020 May 13.

Faculty of Natural Sciences, Vytautas Magnus University, Kaunas LT 44404, Lithuania. Electronic address:

Control of membrane permeability to exogenous compounds by membrane electroporation can lead to cell death, which is related to permanent membrane damage, oxidation stress, leakage of intracellular molecules. In this study, we show that the predominant cell death modality after the application of high voltage electric pulses is related with inability to reseal of initial pores (first stage irreversible electroporation, FirEP). After moderately strong electric pulses, initial pores reseal, however, some cell still die later on due to electric field induced cell stress which leads to delayed cell death (late-stage irreversible electroporation, LirEP).

Role of the time dependence of Boltzmann open probability in voltage-gated proton channels.

Bioelectrochemistry 2020 Aug 2;134:107520. Epub 2020 Apr 2.

Department of Chemistry "Ugo Schiff", Florence University, Via della Lastruccia 3, 50019 Sesto Fiorentino (Firenze), Italy.

The modeling and simulation of experimental families of current-time (I-t) curves of dimeric voltage-gated proton channels and of proton-conducting voltage sensing domains (VSDs) with a minimum of free parameters requires the movement of protons to be controlled by the rate of increase of the Boltzmann open probability p over time in passing from the holding to the depolarizing potential. Families of I-t curves of protomers and proton-conducting VSDs can be satisfactorily fitted by the use of a single free parameter expressing the rate constant k for the increase of p over time. Families of I-t curves of dimeric H1 channels can be fitted by a model that assumes an initial proton current I flowing along the two monomeric units, while they are still operating separately; I is gradually replaced by a slower and more potential-dependent current I flowing when the two monomers start operating jointly under the control of the coiled-coil domain.

Effect of interphase and interpulse delay in high-frequency irreversible electroporation pulses on cell survival, membrane permeabilization and electrode material release.

Bioelectrochemistry 2020 Aug 30;134:107523. Epub 2020 Mar 30.

University of Ljubljana, Faculty of Electrical Engineering, Tržaška cesta 25, 1000 Ljubljana, Slovenia. Electronic address:

To achieve high efficiency of electroporation and to minimize unwanted side effects, the electric field parameters must be optimized. Recently, it was suggested that biphasic high-frequency irreversible electroporation (H-FIRE) pulses reduce muscle contractions. However, it was also shown for sub-microsecond biphasic pulses that the opposite polarity phase of the pulse cancels the effect of the first phase if the interphase delay is short enough. Read More

From algal cells to autofluorescent ghost plasma membrane vesicles.

Bioelectrochemistry 2020 Aug 30;134:107524. Epub 2020 Mar 30.

Frank Reidy Research Center for Bioelectrics, Old Dominion University, Norfolk, VA, USA.

Plasma membrane vesicles can be effective, non-toxic carriers for microscale material transport, provide a convenient model for probing membrane-related processes, since intracellular biochemical processes are eliminated. We describe here a fine-tuned protocol for isolating ghost plasma membrane vesicles from the unicellular alga Dunaliella tertiolecta, and preliminary characterization of their structural features and permeability properties, with comparisons to giant unilamellar phospholipid vesicles. The complexity of the algal ghost membrane vesicles reconstructed from the native membrane material released after hypoosmotic stress lies between that of phospholipid vesicles and cells. Read More
