Design, Synthesis, and Characterization of Fluorescent Cobalamin Analogues with High Quantum Efficiencies

open access: yes, 2016
Cobalamin tethered to fluorescein or Rhodamine 6G has been synthesized and characterized. The fluorophore is conjugated to the ribose-5′-OH of cobalamin through a rigid linker to prevent the fluorophore from folding back through space and interacting ...

Influence of cobalamin scarcity on diatom molecular physiology and identification of a cobalamin acquisition protein

open access: yes, 2012
Diatoms are responsible for ∼40% of marine primary production and are key players in global carbon cycling. There is mounting evidence that diatom growth is influenced by cobalamin (vitamin B12) availability.

Desensitization for Vitamin B12 Hypersensitivity and How to Do It

open access: yesBiomedicines
Vitamin B12 is the common name for a group of cobalamins, which are cobalt corrines. Cobalamins are water-soluble B vitamins. Vitamin B12, as a coenzyme of various enzymes, is an essential component of many key metabolic processes in the body.

Rapid Decolorization of Cobalamin

open access: yes, 2012
The photocatalytic decolorization of cobalamin was carried out in aqueous solution of different types of catalysts including ZnO, TiO2 (Degussa P25), TiO2 (Hombikat UV100), TiO2 (Millennium PC105), and TiO2 (Koronose 2073) by using UVA source of ...

Mitochondrial cobalamin binding proteins in patients with inborn errors of cobalamin metabolism

open access: yes, 2006
Vitamin B12 (cobalamin, Cbl) is required as a cofactor for two human enzymes: methylmalonyl-CoA mutase (MCM) and methionine synthase (MS). Fibroblasts from patients with inborn errors of cobalamin metabolism have been classified into nine distinct ...
