Mammalian class IV alcohol dehydrogenase (stomach alcohol dehydrogenase): structure, origin, and correlation with enzymology.

ALCOHOL DEHYDROGENASE: Structure and Function

Molecular evolution of mammalian class I alcohol dehydrogenase.

Phylogenetic relationship and the rates of evolution of mammalian alcohol dehydrogenases (ADHs) have been studied by using the amino acid sequences from the human (ADH alpha, ADH beta, and ADH gamma), rat, mouse, and horse (ADH E and ADH S). With the maize ADH1 and ADH2 used as references, the patterns of the amino acid replacements in the beta-sheets, alpha-helices, and random coils in each of...

Alcohol Dehydrogenase with

Complexation of alcohol dehydrogenase (ADH) and trypsin with poly(diallyldimethyl-ammonium chloride) (PDADMAC) in dilute electrolyte solution was studied by turbidimetric titration, quasi-elastic light scattering (QELS), and electrophoretic light scattering (ELS). Both QELS and turbidimetric titration show that PDADMAC forms complexes with ADH and trypsin in 0.01M NaCl solution at pH ¢ 6.8 and ...

The alcohol dehydrogenase isoenzyme alcohol dehydrogenase IV as a candidate marker of Helicobacter pylori infection

INTRODUCTION Helicobacter pylori infection is associated with decreased alcohol dehydrogenase (ADH) activity in the gastric mucosa. The decrease in gastric ADH activity depends on the severity of inflammation and mucosal injury. This damage can be a reason of the release of enzyme from gastric mucosa and leads to the increase of the ADH activity in the sera of patients with H. pylori infection....

Yeast Alcohol Dehydrogenase Structure and Catalysis

Yeast (Saccharomyces cerevisiae) alcohol dehydrogenase I (ADH1) is the constitutive enzyme that reduces acetaldehyde to ethanol during the fermentation of glucose. ADH1 is a homotetramer of subunits with 347 amino acid residues. A structure for ADH1 was determined by X-ray crystallography at 2.4 Å resolution. The asymmetric unit contains four different subunits, arranged as similar dimers named...
