Iron-Containing Alcohol Dehydrogenase from Hyperthermophiles. [PDF]
BioTech (Basel)Iron-containing alcohol dehydrogenases (Fe-ADHs) from hyperthermophiles represent a distinct class of oxidoreductases characterized by exceptional thermostability, catalytic versatility, and unique metal-dependent properties.

Obligately Tungsten-Dependent Enzymes─Catalytic Mechanisms, Models and Applications. [PDF]
BiochemistryTungsten-dependent enzymes incorporate a tungsten ion into their active site in the form of a complex with two pyranometallopterin (MPT) molecules, also known as tungsten cofactor (W-co). W-co-containing enzymes are found in several bacteria and archaea,

Novel NADP-linked alcohol–aldehyde/ketone oxidoreductase in thermophilic ethanologenic bacteria [PDF]
Biochemical Journal, 1981 An NADP-specific alcohol--aldehyde/ketone oxidoreductase was detected in cell extracts of Thermoanaerobium brockii and Clostridium thermohydrosulfuricum, but not in Thermobacteroides acetoethylicus or Clostridium thermocellum. The enzyme was purified from Ta. brockii by differential procedures that included heat treatment and an affinity-chromatography

Direct electrochemistry of the Desulfovibrio gigas aldehyde oxidoreductase [PDF]
European Journal of Biochemistry, 2004 This work reports on the direct electrochemistry of the Desulfovibrio gigas aldehyde oxidoreductase (DgAOR), a molybdenum enzyme of the xanthine oxidase family that contains three redox‐active cofactors: two [2Fe‐2S] centers and a molybdopterin cytosine dinucleotide cofactor.

Journal of Biological Chemistry, 1977 Corticosteroid-21-aldehydes were reduced only at C-20 by 20 beta-hydroxysteroid dehydrogenase (EC 1.1.1.53) of Streptomyces hydrogenans, and the reduction occurred by transfer of hydrogen from the B-side of NADH. A kinetic investigation of cortisol, cortisone, cortexolone, and the 21-aldehydes of each indicated: (a) the magnitude of the Michaelis ...

Reduction of Carboxylic Acids by Nocardia Aldehyde Oxidoreductase Requires a Phosphopantetheinylated Enzyme [PDF]
Journal of Biological Chemistry, 2006 Aldehyde oxidoreductase (carboxylic acid reductase (Car)) catalyzes the magnesium-, ATP-, and NADPH-dependent reduction of carboxylic acids to their corresponding aldehydes. Heterologous expression of the car gene in Escherichia coli afforded purified recombinant enzyme with a specific activity nearly 50-fold lower than that of purified native Nocardia

A Versatile Aldehyde: Ferredoxin Oxidoreductase from the Organic Acid Reducing Thermoanaerobacter sp. Strain X514 [PDF]
International Journal of Molecular SciencesAldehyde:ferredoxin oxidoreductases (AORs) have been isolated and biochemically-characterized from a handful of anaerobic or facultative aerobic archaea and bacteria. They catalyze the ferredoxin (Fd)-dependent oxidation of aldehydes to acids.

Journal of Bacteriology, 1995 Desulfovibrio gigas NCIMB 9332 cells grown in ethanol-containing medium with 0.1 microM tungstate contained a benzylviologen-linked aldehyde oxidoreductase. The enzyme was purified to electrophoretic homogeneity and found to be a homodimer with a subunit M(r) of 62,000. It contained 0.68 +/- 0.08 W, 4.8 Fe, and 3.2 +/- 0.2 labile S per subunit.

NMR Identification of an Acyl-adenylate Intermediate in the Aryl-aldehyde Oxidoreductase Catalyzed Reaction [PDF]
Journal of Biological Chemistry, 1998 A new one-pot synthesis was designed to prepare benzoyl-AMP under anhydrous conditions in N,N-dimethylformamide. Reaction of benzoic acid with N,N'-carbonyldiimidazole and subsequently with 5'-adenosyl monophosphate gave the mixed anhydride in 76% isolated yield. The structure of benzoyl-AMP was confirmed by mass spectroscopy and 1H-, 31P-, and 13C-NMR.
