Mutants for most reactions of glycolysis have been described both inEscherichia coliand inSacchavomyces cevevisiaeThe pathway between glucose and pyruvate has three irreversible and seven reversible reactions (Figure 1), and most of the intermediates are needed in biosynthesis. Thus, one might expect mutants in an irreversible step to be impaired in growth on glucose but unimpaired gluconeogenically, and mutants in a reversible step to require supplementation even for gluconeogenic growth. To a first approximation this pattern is found but there are deviations (Table I). For example,E, colimutants blocked between triose-P and phosphoenol-pyruvate do require supplementation (e.g., by glycerol) for growth on lactate (1,2) but phosphoglucose isomerase mutants grow without supplementation by glucose (3) — probably because glucose-6-P and its products are not essential for growth of this organism. Aldolase mutants also do not require supplementation for gluconeogenic growth, and the explanation is unknown; it might relate to other aldolases (see ref. 4). The growth on glucose of a (double) pyruvate kinase mutant occurs because phosphoenolpyruvate is used by the phosphotransferase (PTS) reaction intiating glucose metabolism and such a mutant fails to grown on non-PTS sugars (5).
