  • Title: Hydrolytic and alcoholytic dephosphorylation of nucleotides by acid phosphatase in the presence of ethanol.
    Author: Tomaszewski M, Buchowicz J.
    Journal: Biochem J; 1971 Aug; 124(1):189-92. PubMed ID: 5126469.
    Abstract:
    The effect of ethanol on the activity of acid phosphatase from wheat germ was studied, by using ribonucleoside monophosphates as the enzyme substrates. The nucleotides were effectively degraded to the corresponding nucleosides in the presence of ethanol at all concentrations tested, including a 96% (v/v) solution. However, the nucleotide dephosphorylation was accompanied by the liberation of orthophosphate only when the concentration of ethanol in the assay mixture did not exceed 15%. No inorganic phosphate was liberated when ethanol was present at higher concentrations. Instead, monoethyl phosphate was formed in quantities expected for orthophosphate. The results are explained in terms of phosphatase-catalysed alcoholysis.
