Effect of 2-deoxyglucose on Schizosaccharomyces pombe

Abstract

Megnet, Roland (Institut für Allgemeine Mikrobiologie der Universität, Bern, Switzerland). Effect of 2-deoxyglucose on Schizosaccharomyces pombe. J. Bacteriol. 90:1032-1035. 1965.-Cultivation of Schizosaccaromyces pombe in a medium containing 2-deoxyglucose (100 mug/ml) results in the death of the cells after an initial period of apparently normal growth. At higher deoxyglucose concentration (400 mug/ml), the cells die immediately after inoculation. Only growing cells are killed, and microscopic inspection of the cultures reveals cell-wall fragments of lysed cells. A mutant resistant to 2-deoxyglucose, which cannot use glucose as a carbon source, was found to be partially deficient in hexokinase. The data constitute evidence for the inhibition of some reaction(s) in the synthesis of cell-wall polysaccharides by metabolites of 2-deoxyglucose in this organism.
