A cyclic voltammetry study of the interfacial behaviour of horse liver alcohol dehydrogenase (HLADH) at a Pt surface in a phosphate buffer solution pH 7.0 over the temperature range 273 to 353 K is presented. The surface charge density, resulting from protein adsorption, was shown to be directly proportional to the amount of adsorbed protein (surface concentration). HLADH exhibits very high

Horse liver alcohol dehydrogenase (HLADH) has been found to be a versatile biocatalyst for the desymmetrization of prochiral 3‐arylpentane‐1,5‐diols, based on a two‐step one‐pot oxidation. This procedure has allowed the formation of valuable (S)‐lactones in good to excellent conversions and enantiomeric excess.

The product had an isolated yield of 89.7% or 15.3 g L -1. The predicted range of possible polyamine products by this method is broad since many amino alcohols are putative substrates for HLADH. Examples 1 and 2 in the following table were carried out by a batchwise procedure, ie. the enzyme HLADH and cyclohexanone were added to the catholyte only after the indirect electrochemical hydrogenation of NAD ♁ to NADH, and the cyclohexanol was then determined. HLADH was selected as the best biocatalyst, in terms of specific activity and kinetic parameters.

1991-10-01 2012-04-28 2010-01-01 The RMSF of HLADH at water contents below 10 % (v/v) indicate a rigid enzymatic structure relative to that in the purely aqueous system. This behavior is followed by an increase in enzymatic flexibility at 10 % ( v / v ) water; however, the RMSFs of mixtures of glyceline/water (12.5 to 20 % v / v ) are still much lower than that of the average RMSF of HLADH in water. HLADH was selected as the best biocatalyst, in terms of specific activity and kinetic parameters. Moreover, HLADH catalyzed oxidation of Cbz-ethanolamine was performed and the direct formation of the acid, Cbz-glycine, was observed. Several methods were tested to promote the production of the intermediate product (aldehyde, Auramine O binds to deoxyribonucleic acid (DNA) and horse liver alcohol dehydrogenase (HLADH) in neutral aqueous solution. Binding to DNA is accompanied by modest increases in fluorescence yield and lifetime of the dye whereas binding to HLADH facilitates a dramatic increase in fluorescence.

The migration from a multistep purification protocol for this well-known enzyme to a single-step has been successfully achieved. Several adjustments to the traditional purification procedure for His-tag proteins have been made to retain protein activity.

Human dihydrolipoamide dehydrogenase (hLADH, hE3) deficiency (OMIM# 246900) is an often prematurely lethal genetic disease usually caused by inactive or partially inactive hE3 variants. Here we report the crystal structure of wild-type hE3 at an unprecedented high resolution of 1.75 Å and the structures of six disease-causing hE3 variants at resolutions ranging from 1.44 to 2.34 Å.

Each subunit of this dimeric enzyme binds one molecule of NAD+ and two Zn(II) ions The first-ever isolated alcohol dehydrogenase (ADH) was purified in 1937 from Saccharomyces cerevisiae (brewer's yeast). Many aspects of the catalytic mechanism for the horse liver ADH enzyme were investigated by Hugo Theorell and coworkers.
