Journal of Lipid Research, 1999 We have identified a retinol dehydrogenase (cRDH) that catalyzes the oxidation of 9-cis- but not all-trans-retinol and proposed that this enzyme plays an important role in synthesis of the transcriptionally active retinoid, 9-cis-retinoic acid.

Sulfite: Cytochrome \u3cem\u3ec\u3c/em\u3e Oxidoreductase from \u3cem\u3eThiobacillus novellus\u3c/em\u3e [PDF]
, 2000 Direct oxidation of sulfite to sulfate occurs in various photo- and chemotrophic sulfur oxidizing microorganisms as the final step in the oxidation of reduced sulfur compounds and is catalyzed by sulfite:cytochrome c oxidoreductase (EC1.8.2.1).

Lack of complex I activity in human cells carrying a mutation in MtDNA-encoded ND4 subunit is corrected by the Saccharomyces cerevisiae NADH-quinone oxidoreductase (NDI1) gene [PDF]
, 2001 The gene for the single subunit, rotenone-insensitive, and flavone-sensitive internal NADH-quinone oxidoreductase of Saccharomyces cerevisiae (NDI1) can completely restore the NADH dehydrogenase activity in mutant human cells that lack the essential ...

Oxidoreductases and metal cofactors in the functioning of the earth
Essays in Biochemistry, 2023 Abstract Life sustains itself using energy generated by thermodynamic disequilibria, commonly existing as redox disequilibria. Metals are significant players in controlling redox reactions, as they are essential components of the engine that life uses to tap into the thermodynamic disequilibria necessary for metabolism.

Current Development in Decolorization of Synthetic Dyes by Immobilized Laccases
Frontiers in Microbiology, 2020 The world today is in a quest for new means of environmental remediation as the methods currently used are not sufficient to halt the damage. Mostly, a global direction is headed toward a shift from traditional chemical-based methods to a more ...

Deciphering the Role of Selenoprotein M
Antioxidants, 2023 Selenocysteine (Sec), the 21st amino acid, is structurally similar to cysteine but with a sulfur to selenium replacement. This single change retains many of the chemical properties of cysteine but often with enhanced catalytic and redox activity ...

The genetic basis of energy conservation in the sulfate-reducing bacterium Desulfovibrio alaskensis G20. [PDF]
, 2014 Sulfate-reducing bacteria play major roles in the global carbon and sulfur cycles, but it remains unclear how reducing sulfate yields energy. To determine the genetic basis of energy conservation, we measured the fitness of thousands of pooled mutants of

Tailoring Targeted Therapy to Individual Patients: Lessons to be Learnt from the Development of Mitomycin C [PDF]
, 2007 The modern era of targeted therapeutics offers the potential to tailor therapy to individual patients whose tumours express a specific target. Previous attempts to forecast tumour response to conventional chemotherapeutics based on similar principles ...

Photoprotective role of NADPH:protochlorophyllide oxidoreductase A [PDF]
Proceedings of the National Academy of Sciences, 2008 A homology model of NADPH:protochlorophyllide (Pchlide) oxidoreductase A (POR; E.C. 1.3.33.1) of barley is developed and verified by site-directed mutagenesis. PORA is considered a globular protein consisting of nine α-helices and seven β-strands.
