After 10 min a 100 µl aliquot was removed to determine protein concentration (initial solution).

In an electroylsis process wherein nicotinamide adenine dinucleotide (NAD +) is hydrogenated to (NADH) by an indirect electrochemical reduction in which the electrolysis is carried out in the presence of an electron carrier, the improvement which comprises: employing as the electron carrier a metal complex having a reduction potential which is not more negative than -1.3 volt 1995-01-01 · Horse liver alcohol dehydrogenase (HLADH) was effectively immobilized by adsorption to poly (vinyl alcohol) (PVA), cross-linked polyacrylamide (PAA), or cross-linked chitosan beads (CP). The activity of the immobilized HLADH was estimated from the initial rate of the reduction of cyclohexanone coupled with NADH regeneration via oxidation of 1996-07-30 · The mechanism of oxidation of benzaldehyde to benzoic acid catalyzed by horse liver alcohol dehydrogenase (HLADH) has been investigated using the HLADH structure at 2.1 A resolution with NAD+ and pentafluorobenzyl alcohol in the active site [Ramaswamy et al.

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 Molecular dynamics simulations have been carried out for a period of 10 ns with the dimeric enzyme horse liver alcohol dehydrogenase (HLADH) present as the reactive complex HLADH⋅NAD+⋅ PhCH2O−. Cross-correlation analysis of the trajectory was carried out with the latter from 500 ps to 10 ns. The resulting cross-correlation map allowed the identification of the correlated and Next, the high oxidative ability of HLADH was also exploited to produce Cbz-β-alanine from Cbz-β-amino propanol; a complete conversion was obtained at 72 h in a batch mode.

2000-09-01 HLADH, in order to understand the essential factors in- volved in the productive binding between coenzyme and apo-enzyme [17-20]. In this paper we present the results of detailed kinetic studies on HLADH with PEG-NAD ÷ as coenzyme, and an extension of our modelling studies hLADH pathogenic mutants [13,17]. As calculated in [17], RMSDs greater than 7.51 (in water) or 1.49 Å (in vacuum) provide structures which are signiﬁcantly different from WT-hLADH; all Pathogenic mutations of hLADH cause severe metabolic diseases (atypical forms of E3 deficiency) that often escalate to cardiological or neurological presentations and even premature death; the pathologies are generally accompanied by lactic acidosis. hLADH presents a distinct conformation under acidosis (pH 5.5–6.8) with lower physiological activity and the capacity of generating reactive 119-139 in the dimeric HLADH; Jornvall et al., 1977) and (b) there is no clear evidence for a conserved position in tetrameric ADHs of the inter-subunit contacts observed in the HLADH crystallographic structure. In order to address the question of which residues are actu- ally involved in tetrameric association in yeast ADHs, we have 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. 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.
