Project description:The increasing incidence of fungal infections and damages due to drug-resistant fungi urges the development of new antifungal strategies. The cysteine-rich antifungal proteins from filamentous ascomycetes provide a feasible base for protection against molds due to their potent antifungal activity on them. In contrast to this, they show no or weak activity on yeasts, hence their applicability against this group of fungi is questionable. In the present study a 5.6 kDa anti-yeast protein (NFAP2) is isolated, identified and characterized from the ferment broth of Neosartorya fischeri NRRL 181. Based on a phylogenetic analysis, NFAP2 and its putative homologs represent a new group of ascomycetous cysteine-rich antifungal proteins. NFAP2 proved to be highly effective against tested yeasts involving clinically relevant Candida species. NFAP2 did not cause metabolic inactivity and apoptosis induction, but its plasma membrane disruption ability was observed on Saccharomyces cerevisiae. The antifungal activity was maintained after high temperature treatment presumably due to the in silico predicted stable tertiary structure. The disulfide bond-stabilized, heat-resistant folded structure of NFAP2 was experimentally proved. After further investigations of antifungal mechanism, structure and toxicity, NFAP2 could be applicable as a potent antifungal agent against yeasts.
Project description:Investigation of whole genome gene expression level changes in Spathaspora passalidarum NRRL Y-27907 grown aerobically in xylose, compared to the same strain grown aerobically in glucose. A six array study using total RNA recovered from three separate cultures of Spathaspora passalidarum NRRL Y-27907 grown in glucose and three separate cultures of Spathaspora passalidarum NRRL Y-27907 grown in xylose. Each array measures the expression level of 362,487 probes (average probe length 54.5 +/- 4.0 nt) tiled across the Spathaspora passalidarum NRRL Y-27907 genome with a median spacing distance of 29 nt. During data processing, probes are filtered to include only those probes corresponding to annotated protein-coding genes.

A six array study using total RNA recovered from three separate cultures of Candida tenuis NRRL Y-1498 grown in glucose and three separate cultures of Candida tenuis NRRL Y-1498 grown in xylose. Each array measures the expression level of 363,196 probes (average probe length 53.1 +/- 3.8 nt) tiled across the Candida tenuis NRRL Y-1498 genome with a median spacing distance of 24 nt. During data processing, probes are filtered to include only those probes corresponding to annotated protein-coding genes.
