The Journal of Physiology, EarlyView.Abstract figure legend Beat‐locked mitochondrial ATP transients reveal modular, sex‐specific bioenergetic control during excitation–contraction coupling. A, each action potential activates L‐type CaV1.2 channels, producing a Ca2+ influx that triggers ryanodine receptors (RyR2) and elicits SR Ca2+ release.

Magnesium as a Bioenergetic Checkpoint Linking Mitochondrial Function, Metabolic Disease, and Aging
Aging Cell, Volume 25, Issue 6, June 2026.This review positions magnesium as a central bioenergetic checkpoint that orchestrates mitochondrial function and metabolic resilience. By defining the functional ATP pool and stabilizing mitochondrial performance, magnesium homeostasis serves as a mechanistic link between renal handling, metabolic disease, and the aging process.

Functions of J‐domain proteins in mitochondrial protein biogenesis
Protein Science, Volume 35, Issue 4, April 2026.Abstract Mitochondrial biogenesis and functions depend on the import and assembly of more than 1000 proteins that are made as precursors on cytosolic ribosomes. The majority of these precursor proteins are transported from the ribosome to the translocase of the outer membrane (TOM complex), which constitutes the main entry site for mitochondrial ...

A functionally inactive, cold-stabilized form of the Escherichia coli F1Fo ATP synthase
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2006 An unusual effect of temperature on the ATPase activity of E. coli F1Fo ATP synthase has been investigated. The rate of ATP hydrolysis by the isolated enzyme, previously kept on ice, showed a lag phase when measured at 15 degrees C, but not at 37 degrees C. A pre-incubation of the enzyme at room temperature for 5 min completely eliminated the lag phase,

Mitochondrial permeability transition involves dissociation of F1FO ATP synthase dimers and C‐ring conformation [PDF]
The EMBO Reports, 2017 The impact of the mitochondrial permeability transition (MPT) on cellular physiology is well characterized. In contrast, the composition and mode of action of the permeability transition pore complex (PTPC), the supramolecular entity that initiates MPT, remain to be elucidated.
