Amide and Thioester Synthesis Via Oxidative Coupling of Alcohols with Amines or Thiols Using Alcohol Dehydrogenases

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Alcohol dehydrogenases (ADHs) are best known for reducing ketones to chiral alcohols, but their oxidative potential is rarely exploited. Here, we show that selected ADHs catalyze newly discovered promiscuous transformations: the oxidative coupling of primary alcohols with amines or thiols, enabling the direct and efficient synthesis of a broad range of

Simultaneous expression of an endogenous spermidine synthase and a butanol dehydrogenase from Thermoanaerobacter pseudethanolicus in Clostridium thermocellum results in increased resistance to acetic acid and furans, increased ethanol production and an increase in thermotolerance

Biotechnology for Biofuels and Bioproducts, 2023
Background Sensitivity to inhibitors derived from the pretreatment of plant biomass is a barrier to the consolidated bioprocessing of these complex substrates to fuels and chemicals by microbes.

Substrate Walking for Selective Ene Reduction

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Ene‐reductases (EREDs) efficiently reduce activated C═C bonds. Expanding the current application, they catalyze the selective reduction of highly substituted cyclohexenones. Immobilized, they were scaled to 200 mL, achieving full substrate conversion without enzyme degradation. ABSTRACT Ene‐reductases (EREDs) efficiently reduce activated C═C bonds, but

Construction of a Bacterial Cellulase Cocktail for Saccharification of Regenerated Cellulose and Pretreated Corn Stover

BioResources, 2015
To apply bacterial cellulases for efficient saccharification of biomass, three Clostridium thermocellum cellulases and a Thermoanaerobacter brockii β-1,4-glucosidase were synthesized in Escherichia coli, and the proportions among them were optimized ...

Structure of HsdS subunit from Thermoanaerobacter tengcongensis sheds lights on mechanism of dynamic opening and closing of type I methyltransferase. [PDF]

PLoS ONE, 2011
Type I DNA methyltransferases contain one specificity subunit (HsdS) and two modification subunits (HsdM). The electron microscopy model of M.EcoKI-M₂S₁ methyltransferase shows a reasonable closed state of this clamp-like enzyme, but the structure of the

Engineering New‐to‐Nature Biological Pathways for β,γ‐Alkanediol Synthesis

Advanced Science, Volume 13, Issue 23, 23 April 2026.
β,γ‐Alkanediols are value‐added chemicals to be used as functional solvents, biofuels, and cosmetic components. This work demonstrates a carboligation‐mediated approach for synthesis of linear chain β,γ‐alkanediols in Escherichia coli, namely, hexane‐2,3‐diol (2,3‐HDO) and pentane‐2,3‐diol (2,3‐PDO). The engineered E. coli cells produce 152.2 mm (17.98

Purification and characterization of a thermostable beta-xylosidase from Thermoanaerobacter ethanolicus [PDF]

Journal of Bacteriology, 1992
A highly thermostable beta-xylosidase, exhibiting similarly high activities for arylxylose and arylarabinose, was purified (72-fold) to gel electrophoretic homogeneity from the ethanologenic thermophilic anaerobe Thermoanaerobacter ethanolicus. The isoelectric point is pH 4.6; the apparent molecular weight is around 165,000 for the native enzyme (gel ...

Correlation of Genomic and Physiological Traits of Thermoanaerobacter Species with Biofuel Yields [PDF]

Applied and Environmental Microbiology, 2011
ABSTRACT Thermophilic anaerobic noncellulolytic Thermoanaerobacter species are of great biotechnological importance in cellulosic ethanol production due to their ability to produce high ethanol yields by simultaneous fermentation of hexose and pentose. Understanding the genome structure of these species is
