Association of the eukaryotic V1VO ATPase subunits a with d and d with A [PDF]

, 2009
Owing to the complex nature of V1VO ATPases, identification of neighboring subunits is essential for mechanistic understanding of this enzyme. Here, we describe the links between the V1 headpiece and the VO-domain of the yeast V1VO ATPase via subunit A ...

Branchial localization of acid (A‐type) and base (B‐type) excreting ionocytes in Amazonian stenohaline freshwater Potamotrygon ray

Journal of Fish Biology, EarlyView.
Abstract The branchial epithelium of Potamotrygon—a member of the only strictly freshwater elasmobranch family Potamotrygonidae—was observed via immunohistochemistry, and two distinct forms of ionocytes were identified. The acid (A‐type) and base (B‐type) secreting cells with respective basolateral–apical localizations of Na+/K+‐ATPase–Na+/H+ exchanger

The microbiologist’s guide to membrane potential dynamics [PDF]

, 2020
All cellular membranes have the functionality of generating and maintaining the gradients of electrical and electrochemical potentials. Such potentials were generally thought to be an essential but homeostatic contributor to complex bacterial behaviors ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

A new type of Na+-driven ATP synthase membrane rotor with a two-carboxylate ion-coupling motif [PDF]

, 2013
: The anaerobic bacterium Fusobacterium nucleatum uses glutamate decarboxylation to generate a transmembrane gradient of Na+. Here, we demonstrate that this ion-motive force is directly coupled to ATP synthesis, via an F1Fo-ATP synthase with a novel Na ...

The Volatile Pentadecane From Bacillus Alleviates Plant Iron Deficiency Through Activating the Reduction‐Based Fe Uptake System

Plant Biotechnology Journal, EarlyView.
ABSTRACT Iron (Fe) is an essential micronutrient for plant growth and development. Rhizosphere microorganisms play crucial roles in plant Fe nutrition, yet the underlying mechanisms remain largely unknown. Here, we assessed the effect of the volatile organic compounds (VOCs) produced by Bacillus velezensis SQR9 on Fe uptake in Arabidopsis, elucidated ...

Effect of Tentoxin on the Activation and on the Catalytic Reaction of Reconstituted H+-ATPase from Chloroplasts [PDF]

, 1992
The proton-translocating ATPase from chloroplasts, CF0F1, was isolated, purified and reconstituted into asolectin liposomes. The effect of the energy transfer inhibitor, tentoxin, on different functions of the enzyme was investigated.

Pangenome Analysis Reveals Structural Variations Associated With Citric Acid Accumulation in Prunus mume

Plant Biotechnology Journal, EarlyView.
ABSTRACT Pangenome can reveal a large number of variations, providing a more comprehensive view of the genetic diversity of species that a single reference genome cannot surpass. Here, we assembled the haplotype telomere‐to‐telomere genome and 10 chromosome‐level genomes, integrated with two previously reported genomes, and constructed a graph ...

Structures and proton-pumping strategies of mitochondrial respiratory enzymes [PDF]

, 2001
Enzymes of the mitochondrial respiratory chain serve as proton pumps, using the energy made available from electron transfer reactions to transport protons across the inner mitochondrial membrane and create an electrochemical gradient used for the ...
