Lysine Biosynthesis Defines a Metabolic Checkpoint for Gibberellin‐Mediated Growth in Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT Lysine represents a metabolic hub linking mitochondrial energy status with amino acid catabolism, yet its role in coordinating plant growth and development remains poorly characterised. The dapat mutant, which is deficient in L,L‐diaminopimelate aminotransferase (DAPAT), exhibits severe growth inhibition associated with broad metabolic ...

Origin and Evolution of Flavin-Based Electron Bifurcating Enzymes

Frontiers in Microbiology, 2018
Twelve evolutionarily unrelated oxidoreductases form enzyme complexes that catalyze the simultaneous coupling of exergonic and endergonic oxidation–reduction reactions to circumvent thermodynamic barriers and minimize free energy loss in a process known ...

Skeletal muscle‐specific myostatin overexpression promotes muscle oxidative capacity and fatigue resistance in transgenic mice

Experimental Physiology, EarlyView.
Abstract In addition to controlling muscle mass, myostatin may support oxidative metabolism and endurance. Loss of function through gene knockout or post‐natal blockade generally lowers muscle oxidative capacity and increases fatigability. These observations imply that myostatin activation could promote a more oxidative and less fatigable muscle ...

Flavin-Based Electron Bifurcation, Ferredoxin, Flavodoxin, and Anaerobic Respiration With Protons (Ech) or NAD+ (Rnf) as Electron Acceptors: A Historical Review

Frontiers in Microbiology, 2018
Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more ...

Magnetic resonance and fluorescence studies on pyruvate dehydrogenase complexes and their small molecular weight constituents

, 1976
The articles presented in this thesis do not describe at first glance one well-defined subject. They are, however, in fact connected by one central theme: the study of large enzyme aggregates by molecular physical methods.

Fluorescence and optical characteristics of reduced flavines and flavoproteins

, 1974
The fluorescence and absorption properties of a series of reduced flavoproteins have been measured and compared with the properties of suitable model compounds.Contrary to common belief, a number of reduced flavoproteins have been found to exhibit ...

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Hypoxic vasoconstriction of partial muscular intra-acinar pulmonary arteries in murine precision cut lung slices

Respiratory Research, 2006
Background Acute alveolar hypoxia causes pulmonary vasoconstriction (HPV) which serves to match lung perfusion to ventilation. The underlying mechanisms are not fully resolved yet.
