Molecular dynamics simulations of the oxidation of benzyl alcohol by horse liver alcohol dehydrogenase (HLADH) have been carried out. The following three states have been studied: HLADH.PhCH (2)OH.NAD (+) (MD1), HLADH.PhCH (2)O (-).NAD (+) (MD2), and HLADH.PhCHO.NADH (MD3). MD1, MD2, and MD3 simulations were carried out on one of the subunits of The EE subunit of horse liver alcohol dehydrogenase (HLADH-EE) has been subcloned in pRSETb vector to generate a fusion His-tag protein.

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
S1 †) as well as EtOH and i PrOH were determined (Table S1 †) showing that HLADH exhibits a reasonable apparent K M value of 23 mM towards 1,4-BD In the HLADH molecule, the position of the active site is well known: the enzyme subunits are divided into two different domains (the coenzyme binding domain and the catalytic domain). These domains are separated by a crevice that contains a wide and deep pocket which is the binding site for the substrate and the nicotinamide moiety of the coenzyme [ [ 24 ] ]. 2000-09-01 HLADH, in order to understand the essential factors in- volved in the productive binding between coenzyme and apo-enzyme [17-20].

Studies in Natural Products Chemistry, 17 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 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.
