The cysteine proteinase activity secreted by cultured mam mary gland was characterized to determine its relationship to a similar enzyme secreted by expiants of mouse mammary tumors. Enzymic characterization showed that the secreted enzyme was similar to the lysosomal cysteine proteinase cathepsin B, and physical characterization showed properties identical to a stable cysteine proteinase secre...
Crystals of the molecular complex between the esterified tripeptide fragment of pepstatin and the aspartyl proteinase penicillopepsin are isomorphous with crystals of native penicillopepsin. The difference electron-density map at 1.8-A resolution, computed by using the amplitude differences and refined phases of reflections from the crystal of native penicillopepsin, unambiguously showed the bi...
The widespread occurrence of vaginal candidiasis and the development of resistance against anti-fungal agents has stimulated interest in understanding the pathogenesis of this disease. The aim of our work was to characterize, in an animal model of vaginal candidiasis, the mechanisms that play a role in the induction of mucosal immunity against C. albicans and the interaction between innate and ...
Candida albicans is an opportunistic fungal pathogen that causes severe systemic infections in immunosuppressed individuals. C. albicans resistance to antifungal drugs is a severe problem in patients receiving prolonged therapy. Moreover, trailing yeast growth, which is defined as a resistant MIC after 48 h of incubation with triazole antifungal agents but a susceptible MIC after 24 h, has been...
Evidence for degradation of gastrointestinal mucin by Candida albicans secretory aspartyl proteinase
Medically important yeasts of the genus Candida secrete aspartic proteinases (Saps), which are of particular interest as virulence factors. Like Candida albicans, Candida tropicalis secretes in vitro one dominant Sap (Sapt1p) in a medium containing bovine serum albumin (BSA) as the sole source of nitrogen. Using the gene SAPT1 as a probe and under low-stringency hybridization conditions, three ...
Cell proliferation has been found to correlate with increased secretion of proteinases, such as plasminogen activator, in several different cell populations. In addition, the shape of the cell may also play a role in regulating proteinase secretion. However, the relationship between cell proliferation, cell shape and proteinase secretion has not been studied in diploid epithelial (E) cells cult...
