Analyzing the effect of ion binding to the membrane-surface on regulating the light-induced transthylakoid electric potential (ΔΨm)

Frontiers in Plant Science, 2022
The transthylakoid membrane potential (ΔΨm) is essential because it can drive the ATP synthesis through the CF0–CF1 type of ATP-synthase in chloroplasts as an energetic equivalent similar to ΔpH.

Deciphering the Role of Ion Channels in Early Defense Signaling against Herbivorous Insects

Cells, 2021
Plants and insect herbivores are in a relentless battle to outwit each other. Plants have evolved various strategies to detect herbivores and mount an effective defense system against them.

A Novel Cryptic Clostridial Peptide That Kills Bacteria by a Cell Membrane Permeabilization Mechanism

Microbiology Spectrum, 2022
This work reports detailed characteristics of the antimicrobial peptide Intestinalin (P30), which is derived from the LysC enzyme of Clostridium intestinale strain URNW. The peptide shows a broader antibacterial spectrum than the parental enzyme, showing

Different resting membrane potentials in posterior parietal cortex and prefrontal cortex in the view of recurrent synaptic strengths and neural network dynamics

Frontiers in Cellular Neuroscience, 2023
In this study, we introduce the importance of elevated membrane potentials (MPs) in the prefrontal cortex (PFC) compared to that in the posterior parietal cortex (PPC), based on new observations of different MP levels in these areas. Through experimental

Calcium‐ and voltage‐driven atrial alternans: Insight from [Ca]i and Vm asynchrony

Physiological Reports, 2023
Cardiac alternans is defined as beat‐to‐beat alternations in contraction strength, action potential duration (APD), and Ca transient (CaT) amplitude. Cardiac excitation–contraction coupling relies on the activity of two bidirectionally coupled excitable ...

Encoding Membrane-Potential-Based Memory within a Microbial Community.

Cell Systems, 2020
Cellular membrane potential plays a key role in the formation and retrieval of memories in the metazoan brain, but it remains unclear whether such memory can also be encoded in simpler organisms like bacteria.

Lipophilic Cations Rescue the Growth of Yeast under the Conditions of Glycolysis Overflow

Biomolecules, 2020
Chemicals inducing a mild decrease in the ATP/ADP ratio are considered as caloric restriction mimetics as well as treatments against obesity. Screening for such chemicals in animal model systems requires a lot of time and labor. Here, we present a system

Effect of sodium humate on membrane potential in internodal cells of Nitellopsis obtusa

Acta Societatis Botanicorum Poloniae, 2014
Membrane potential and resistance changes in Nitellopsis obtusa induced by Na-humate as a function of external pH were investigated. The administration of Na-humate at concentrations of 12.5, 25, 50 and 100 mg dm-3 brought about a hyperpolarization of ...

Effects of Matrix pH on Spontaneous Transient Depolarization and Reactive Oxygen Species Production in Mitochondria

Frontiers in Cell and Developmental Biology, 2021
Reactive oxygen species (ROS) oxidize surrounding molecules and thus impair their functions. Since mitochondria are a major source of ROS, suppression of ROS overproduction in the mitochondria is important for cells.

Requirement of a Membrane Potential for the Posttranslational Transfer of Proteins into Mitochondsria [PDF]

, 1982
Posttranslational transfer of most precursor proteins into mitochondria is dependent on energization of the mitochondria. Experiments were carried out to determine whether the membrane potential or the intramitochondrial ATP is the immediate energy ...
