The Reaction of 2-Methyl-1, 4-naphthoquinone with Yeast Alcohol Dehydrogenase

Acid-Base Catalysis in the Yeast Alcohol Dehydrogenase Reaction*

The effect of pH on steady state kinetic parameters for the yeast alcohol dehydrogenase-catalyzed reduction of aldehydes and oxidation of alcohols has been studied. The oxidation of p-CH3 benzyl alcohol-l, l-h2 and -l,l-dz by NAD+ was found to be characterized by large deuterium isotope effects (&J&n = 4.1 f 0.1) between pH 7.5 and 9.5, indicating a rate-limiting hydride transfer step in this p...

Acid-base catalysis in the yeast alcohol dehydrogenase reaction.

The effect of pH on steady state kinetic parameters for the yeast alcohol dehydrogenase-catalyzed reduction of aldehydes and oxidation of alcohols has been studied. The oxidation of p-CH3 benzyl alcohol-1,1-h2 and -1,1-d2 by NAD+ was found to be characterized by large deuterium isotope effects (kH/kD = 4.1 plus or minus 0.1) between pH 7.5 and 9.5, indicating a rate-limiting hydride trahsfer st...

The reaction of methyl mercury nitrate with the sulfhydryl groups of yeast glyceraldehyde-3-phosphate dehydrogenase.

The importance of two of the thiol groups of yeast triosephosphate dehydrogenase for its activity haa been shown by the abolition of activity and diphosphopyridine nucleotide binding by the addition of 2 equivalents of p-chloromercuribenzoate (PCMB) (1, 2). The reaction of methyl mercury nitrate with this enzyme has been found to be anomalous in the sense that this mercury compound, unlike PCMB...
