Direct electrochemical reduction of ferredoxin promoted by Mg2+

Reduction of cobamides by reduced ferredoxin.

Reduced ferredoxin is capable of reducing nonenzymatitally cyano-Bit. Spectral studies have shown that BE, (a l-electron reduced derivative of the vitamin) accumulates in the reaction although the formation of methyl-B12 was observed upon the addition of methyl iodide to the incubation. The data indicate that reduction of cyano-Blz by reduced ferredoxin results in the transient formation of B12...

Direct electrochemical reduction of hemin in imidazolium-based ionic liquids

The direct electrochemical reduction of hemin, protoporphyrin(IX) iron(III) chloride, ligated with strong or weak heterocyclic bases, was investigated in the ionic liquids (IL), 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) and 1-octyl-3methylimidazolium hexafluorophosphate ([omim][PF6]), using cyclic voltammetry and chronocoulometry. Hemin complexed with N-methylimidazole (NMI)...

The Direct Electrochemical Investigation of Redox Enzymes

Even though the use of enzymes as useful analytical reagents when immobilized onto a transducer such as an electrochemical device has been reported in the literature for nearly two decades, the direct, i.e. unmediated electrochemistry of enzymes is, nevertheless, a rather recent development. Efforts will be made to introduce the fundamental basis for protein-surface interactions with emphas...
