Synthetically prepared glycooligosaccharides mimicking Candida albicans cell wall glycan antigens--novel tools to study host-pathogen interactions.

abstract：:The mechanistic details of mtDNA maintenance in petite-negative yeasts have remained largely unexplored. We report here that the DNA helicase Hmi1p plays a crucial role in mtDNA stability in Candida albicans. Like its counterpart in Saccharomyces cerevisiae, Hmi1p in C. albicans (CaHmi1p) contains a C-terminal mitocho...
