Electron Microscopic Analysis and Structural Characterization of Novel NADP(H)-Containing Methanol: N,N'-Dimethyl-4-Nitrosoaniline Oxidoreductases from the Gram-Positive Methylotrophic Bacteria Amycolatopsis methanolica and Mycobacterium gastri MB19 [PDF]

, 1993
The quaternary protein structure of two methanol:N,N'-dimethyl-4-nitrosoaniline (NDMA) oxidoreductases purified from Amycolatopsis methanolica and Mycobacterium gastri MB19 was analyzed by electron microscopy and image processing.

Membrane electrochemical reactors (MER) for NADH regeneration in HLADH-catalysed synthesis: comparison of effectiveness [PDF]

, 2004
Two membrane electrochemical reactors(MER) were designed and applied to HLADH-catalysed reduction of cyclohexanone to cyclohexanol. The regeneration of the cofactor NADH was ensured electrochemically, using either methyl viologen or a rhodium complex as

Sortase A-mediated crosslinked short-chain dehydrogenases/reductases as novel biocatalysts with improved thermostability and catalytic efficiency

Scientific Reports, 2017
(S)-carbonyl reductase II (SCRII) from Candida parapsilosis is a short-chain alcohol dehydrogenase/reductase. It catalyses the conversion of 2-hydroxyacetophenone to (S)-1-phenyl-1,2-ethanediol with low efficiency.

Dynamic exchange strategy for enzyme immobilization in Zr-based metal-organic frameworks for green synthesis of β-lactam antibiotics

Green Chemical Engineering
Penicillin G acylase (PGA), a crucial biocatalyst in β-lactam antibiotic synthesis, has been significantly limited in its industrial application due to inherent stability issues. To address this critical challenge, efficient immobilization strategies and

Localization of xanthine oxidoreductase activity using the tissue protectant polyvinyl alcohol and final electron acceptor Tetranitro BT. [PDF]

Journal of Histochemistry & Cytochemistry, 1991
We have detected xanthine oxidoreductase activity in unfixed cryostat sections of rat and chicken liver, rat duodenum, and bovine mammary gland using the tissue protectant polyvinyl alcohol, the electron carrier 1-methoxyphenazine methosulfate, the final electron acceptor Tetranitro BT, and hypoxanthine as a substrate.

Synthesis of pyruvate: ferredoxin oxidoreductase and alcohol dehydrogenase E enzymes during Giardia intestinalis excystation.

Biomedica : revista del Instituto Nacional de Salud, 2010
Giardia intestinalis is a unicellular parasite of worldwide distribution. It causes an intestinal illness known as giardiasis, and it is probably the earliest diverging eukaryotic microorganism. Previously, changes have been reported in the expression of mRNAs at several stages of the life cycle; however specific enzymatic activity changes have not ...

Proteomic analysis of Clostridium thermocellum core metabolism: relative protein expression profiles and growth phase-dependent changes in protein expression

BMC Microbiology, 2012
Background Clostridium thermocellum produces H2 and ethanol, as well as CO2, acetate, formate, and lactate, directly from cellulosic biomass. It is therefore an attractive model for biofuel production via consolidated bioprocessing.
