Abstract
THE respiration-deficient mutant of baker's yeast, Saccharomyces cerevisiae R XII A, induced by high-temperature cultivation, was used for examining the point of action of oxygen in the Pasteur effect. The mutant was identical with the petite colonie mutant described by Ephrussi1 and Raut2. The argument was that, if oxygen acted directly on some enzyme involved in glucose degradation (for example, glyceraldehyde phosphate dehydrogenase), it would decrease the rate of glucose catabolism even in the mutant lacking essential components of the cytochrome system.
