Vitamin C, water-soluble, carbohydrate-like substance that is involved in certain metabolic processes of animals. Although most animals can synthesize vitamin C, it is necessary in the diet of some, including humans and other primates, in order to preven

The number of known three-dimensional structures of vitamin B6-dependent enzymes has doubled in the past two years. A fourth type of fold for B6-dependent enzymes, involving a TIM-barrel domain, has been discovered. Alanine racemase is the first known representative of this new fold. Significan...
We present a theoretical study of the geometric structure of Co(corrin)(L)(R)+ (R = CH3, i-C3H7 and adenosyl and L = NH3, pyridine and 5,6-dimethylbenzimidazole) as model systems for the vitamin B12 coenzyme. We have optimized the geometries of nine corrin derivatives with axial ligan...

The ATP-binding cassette (ABC) transporter BtuCD mediates the uptake of vitamin B12 across the inner membrane of Escherichia coli. Previous structures have shown the conformations of apo states, but the transport mechanism has remained unclear. Here we r
The incubation of erythrocyte ghosts with mixtures of vitamins A + D3, A + E, A + K1 , produces decrease or increase of fluorescence anisotropy r of the DPH probe, depending on the vitamin/vitamin ratio. We found a correlation between the order parameter S and cell fusion phenomena observe...
