In cells harvested from exponential growth on glucose-containing medium the specific activity of the enzyme is found to be 20-30% lower than the specific activity observed in media without glucose, containing acetate or ethanol as the carbon source. X-Prolyl-dipeptidyl aminopeptidase is not inactivated after the addition of glucose to stationary phase cells. Growth of the yeast on poor nitrogen sources or under nitrogen-starvation results in a three- to fourfold increase in the level of the enzyme.", }
