Effects of m-Cl-peroxy benzoic acid on glycolysis in Saccharomyces cerevisiae.

Concentrations of m-Cl-peroxy benzoic acid (CPBA) higher than 0.1 mM decrease the ATP-content of Saccharomyces cerevisiae in the presence of glucose in 1 min to less than 10% of the initial value. In the absence of glucose, 1.0 mM CPBA is necessary for a similar effect. After the rapid loss of ATP in the first min in the presence of glucose caused by 0.2 mM CPBA, the ATP-content recovers to nearly the initial value after 10 min. Aerobic glucose consumption and ethanol formation from glucose are both completely inhibited by 1.0 mM CPBA. Assays of the activities of nine different enzymes of the glycolytic pathway as well as analysis of steady state concentrations of metabolites suggest that glyceraldehyde-3-phosphate dehydrogenase is the most sensitive enzyme of glucose fermentation. Phosphofructokinase and alcohol dehydrogenase are slightly less sensitive. Incubation for 1 or 10 min with concentrations of 0.05 to 0.5 mM CPBA causes a) inhibition of glyceraldehyde-3-phosphate dehydrogenase, b) decrease of the ATP-content and c) a decrease of the colony forming capacity. From these findings it is concluded that the disturbance of the ATP-producing glycolytic metabolism by inactivation of glyceraldehyde-3-phosphate dehydrogenase may be an explanation for cell death caused by CPBA.
