Glutathione reductase directly mediates the stimulation of yeast glucose-6-phosphate dehydrogenase by GSSG.

Yeast glucose-6-phosphate dehydrogenase was inhibited by low NADPH concentrations in cell-free extracts, and de-inhibited by GSSG; extensive dialysis of the crude extract did not diminish the GSSG effect. Immunoprecipitation of glutathione reductase abolished the de-inhibition of glucose-6-phosphate dehydrogenase by GSSG. Purified glucose-6-phosphate dehydrogenase was inhibited by NADPH but not de-inhibited by GSSG, and upon addition of pure glutathione reductase GSSG completely de-inhibited the glucose-6-phosphate dehydrogenase.

The metabolism of acetone in the pregnant rat.

The administration of a single dose of acetone (100 mg/kg bw) to virgin and 21-day pregnant rats resulted in the appearance of relatively high concentrations of 1,2-propanediol, acetol and methylglyoxal in plasma and liver. In the fetuses no methylglyoxal was detectable. The acetone metabolism curves tend to indicate that the capacity for acetone disposal may be enhanced in the 48 hr-fasted pregnant rat, thus enabling the animal to re-use acetone metabolically, possibly for accelerated gluconeogenesis.
