Characterization of a mutant of the yeast Candida maltosa defective in catabolite inactivation of gluconeogenetic enzymes

A spontaneous mutant of the yeast Candida maltosa SBUG 700 was isolated showing pseudohyphal marphology under all growth conditions tested. The C. maltosa PHM mutant takes up glucose with the kinetics of C. maltosa SBUG 700 and starved cells contain the same cyclic AMP concentration. Addition of glucose to the PHM mutant does not result in an increase of the intracellular cyclic AMP level and in catabolite inactivation of fructose-1,6-bisphosphatase, malate dehydrogenase and phosphoenolpyruvate carboxykinase. However, addition of 2,4-dinitrophenol is followed by a rapid, transient increase of the cyclic AMP level in the mutant cells, but not by catabolite inactivation. These results show that a common mechanism might be responsible for catabolite inactivation and glucose-induced cAMP signaling or that glucose-induced cAMP signaling is required for catabolite inactivation in C. maltosa.
