Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1998 This paper gives an overview of a lecture scheduled for the opening of the 10th European Bioenergetics Congress. In this lecture I plan to first reflect on the accomplishments of some of the individuals who were involved in research on the ATP synthase during the past 50 years.

FEBS Letters, EarlyView.Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Redox Biology, 2021 Reactive oxygen species (ROS) are a common product of active mitochondrial respiration carried in mitochondrial cristae, but whether cristae shape influences ROS levels is unclear.

A working model for cytoplasmic assembly of H/ACA snoRNPs
FEBS Letters, EarlyView.Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

The Journal of Clinical Investigation, 2022 In hypertrophied and failing hearts, fuel metabolism is reprogrammed to increase glucose metabolism, especially glycolysis. This metabolic shift favors biosynthetic function at the expense of ATP production.

Cryo-EM structure of the mammalian ATP synthase tetramer bound with inhibitory protein IF1
Science, 2019 ATP production under lockdown Cellular processes must respond to change, often by speeding up, slowing down, or stopping altogether. Adenosine triphosphate (ATP) synthases use a transmembrane proton gradient to produce ATP, but this reaction can go in ...

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Deregulation of mitochondrial F1FO-ATP synthase via OSCP in Alzheimer’s disease
Nature Communications, 2016 F1FO ATP synthase is a critical enzyme for the maintenance of mitochondrial function. Here the authors demonstrate that loss of the F1FO-ATP synthase subunit OSCP and the interaction of OSCP with Aβ peptide in Alzheimer’s disease patients and mouse ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
