Abstract

A glucosephosphate isomeraseless mutant ofSaccharomyces cerevisiae was able to accumulate glucose-6-phosphate when incubated with glucose. Transport ofd-xylose was measured in the glucose-6-phosphate charged cells and compared with untreated cells. Even at an intracellular concentration of 15 mM, inhibition of the transport did not surpass 20%. It is concluded that glucose-6-phosphate is not the regulatory metabolite of hexose transport in yeast.
