Subunit rotation in a single FoF1-ATP synthase in a living bacterium monitored by FRET [PDF]

, 2011
FoF1-ATP synthase is the ubiquitous membrane-bound enzyme in mitochondria, chloroplasts and bacteria which provides the 'chemical energy currency' adenosine triphosphate (ATP) for cellular processes. In Escherichia coli ATP synthesis is driven by a proton motive force (PMF) comprising a proton concentration difference {\Delta}pH plus an electric ...

Fast ATP-dependent Subunit Rotation in Reconstituted FoF1-ATP Synthase Trapped in Solution [PDF]

arXiv, 2021
FoF1-ATP synthases are ubiquitous membrane-bound, rotary motor enzymes that can catalyze ATP synthesis and hydrolysis. Their enzyme kinetics are controlled by internal subunit rotation, by substrate and product concentrations, by mechanical inhibitory mechanisms, but also by the electrochemical potential of protons across the membrane.

Targeting miRNA‐1a and miRNA‐15b: A Novel Combinatorial Strategy to Drive Adult Cardiac Regeneration

Advanced Science, EarlyView.
The article explores a novel therapeutic strategy for cardiac regeneration by targeting miRNA‐1a and miRNA‐15b. Combinatorial inhibition of miR‐1a and miR‐15b enhances cardiomyocyte proliferation, improves heart function, and reduces fibrosis in myocardial infarction models.

Expression of Genes Encoding the Enzymes for Glycogen and Trehalose Metabolism in L3 and L4 Larvae of Anisakis simplex

Journal of Parasitology Research, 2015
Trehalose and glycogen metabolism plays an important role in supporting life processes in many nematodes, including Anisakis simplex. Nematodes, cosmopolitan helminths parasitizing sea mammals and humans, cause a disease known as anisakiasis.

Detecting substeps in the rotary motors of FoF1-ATP synthase by Hidden Markov Models [PDF]

, 2007
FoF1-ATP synthase is the enzyme that provides the 'chemical energy currency' adenosine triphosphate, ATP, for living cells. The formation of ATP is accomplished by a stepwise internal rotation of subunits within the enzyme. We monitor subunit rotation by a single-molecule fluorescence resonance energy transfer (FRET) approach using two fluorophores ...

Glycogen Synthase Kinase (GSK) 3β phosphorylates and protects nuclear myosin 1c from proteasome-mediated degradation to activate rDNA transcription in early G1 cells [PDF]

, 2014
Nuclear myosin 1c (NM1) mediates RNA polymerase I (pol I) transcription activation and cell cycle progression by facilitating PCAF-mediated H3K9 acetylation, but the molecular mechanism by which NM1 is regulated remains unclear.

Modeling work-speed-accuracy trade-offs in a stochastic rotary machine [PDF]

Phys. Rev. E 101, 032110 (2020), 2019
Molecular machines are stochastic systems that catalyze the energetic processes keeping living cells alive and structured. Inspired by the examples of F1-ATP synthase and the bacterial flagellum, we present a minimal model of an externally driven stochastic rotary machine.

Purification of Starch Granules from Arabidopsis Leaves and Determination of Granule-Bound Starch Synthase Activity [PDF]

, 2014
Starch constitutes the most important carbon reserve in plants and is composed of branched amylopectin and linear amylose. The latter is synthesized exclusively by the Granule-Bound Starch Synthase (GBSS, EC 2.4.1.21).
