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).

Improved catalytic activity of ruthenium–arene complexes in the reduction of NAD+ [PDF]
A series of neutral Ru-II half-sandwich complexes of the type [(eta(6)-arene)Ru(N,N')Cl] where the arene is para-cymene (p-cym), hexamethylbenzene (hmb), biphenyl (bip), or benzene (bn) and N,N' is N-(2-aminoethyl) -4-(trifluoromethyl)benzenesulfonamide (

Remnants of an ancient metabolism without phosphate [PDF]
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
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.
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
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,
