Iron-sulfur flavoenzymes: the added value of making the most ancient redox cofactors and the versatile flavins work together

open access: yesOpen Biology, 2021
Iron-sulfur (Fe-S) flavoproteins form a broad and growing class of complex, multi-domain and often multi-subunit proteins coupling the most ancient cofactors (the Fe-S clusters) and the most versatile coenzymes (the flavin coenzymes, FMN and FAD).

Vitamin D Auto-/Paracrine System Is Involved in Modulation of Glucocorticoid-Induced Changes in Angiogenesis/Bone Remodeling Coupling

open access: yesInternational Journal of Endocrinology, 2020
Osteoporosis is a devastating side effect of chronic glucocorticoid (GC) treatment. Despite the crucial role of vitamin D (VD) in bone homeostasis, the precise molecular mechanisms of its action on GC-induced disturbances of bone remodeling remain ...

Remnants of an ancient metabolism without phosphate [PDF]

open access: yes, 2017
Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.

The “great” controlling nucleotide coenzymes

open access: yesIUBMB Life - A Journal of the International Union of Biochemistry and Molecular Biology, 2019
Nucleotide coenzymes dot the map of metabolic pathways providing energy to drive the reactions of the pathway and play an important role in regulating and controlling energy metabolism through their shared potential energy, which is widely unobserved due

Coenzyme A thiosulfonate (coenzyme A disulfide-S,S-dioxide), an affinity analog of coenzyme A.

open access: yesJournal of Biological Chemistry, 1982
The structure of the CoA affinity analog-oxidized CoA disulfide (o-CoAS2) (Collier, G. E., and Nishimura, J. S. (1978) J. Biol. Chem. 253, 4938-4939) has been deduced to be that of the thiosulfonate of CoA, i.e. coenzyme A disulfide-S,S-dioxide. This deduction is based on several considerations among which are: the cleavage of o-CoAS2 by dithiothreitol

The content of riboflavin and its coenzymes forms in the brain of rats of different ages

open access: yesJournal of Education, Health and Sport, 2017
The content of total riboflavin and its coenzymes (FAD and FMN) in the brain homogenates of rats of different ages by means of fluorimetric ion exchange chromatography was determined. The experiment included 3 age groups of rats: 3 months, 10-12 months,
