Abstract:
According to different metabolic situations in various stages of Candida albicans pathogenesis the regulation of carbohydrate metabolism was investigated. We report the genetic characterization of all major C. albicans gluconeogenic and glyoxylate cycle genes (fructose-1,6-bisphosphatase, PEP carboxykinase, malate synthase and isocitrate lyase) which were isolated after functional complementation of the corresponding Saccharomyces cerevisiae deletion mutants. Remarkably, the regulation of the heterologously expressed C. albicans gluconeogenic and glyoxylate cycle genes was similar to that of the homologous S. cerevisiae genes. A C. albicans DeltaCafbp1 deletion strain failed to utilize non-fermentable carbon sources but hyphal growth was not affected. Our results show that regulation of gluconeogenesis in C. albicans is similar to that of S. cerevisiae and that the current knowledge on how gluconeogenesis is regulated will facilitate the physiological understanding of C. albicans.
