Induction of N-acetyl-D-glucosamine catabolic enzymes and germinative response in Candida albicans.
The regulation of N-acetylglucosamine catabolic enzymes was studied in both yeast and germ tube forms of the dimorphic fungus Candida albicans. The induction pattern of these enzymes was the same for yeast cells incubated at 28 degrees C and in cells incubated at 37 degrees C which formed germ tubes. However, the level of activity of these enzymes in germ tube stage is lower as compared to yeast phase cells. A strain of C. albicans that did not form germ tubes was endowed with a pronounced ability for induction of N-acetylglucosamine catabolic enzymes. This result suggests that germ tube formation and N-acetylglucosamine metabolism are mutually exclusive events.
