A Candida albicans aspartic proteinase (CAP), one of the secretory proteinases of Candida albicans, is thought to be a possible virulence factor in Candida albicans infection. Whereas endothelin-1 is found as an endothelium-derived strong vasoconstrictive peptide, it is known to have a role in the maintenance of vascular homeostasis and tissue survival. Endothelin-1 is generated from a precursor form of endothelin-1, the so-called big endothelin-1. It has recently been reported that cathepsin D, E and pepsin, which are aspartic proteinases, convert big endothelin-1 to endothelin-1. In this study, the relationship between CAP and big endothelin-1 was studied. High performance liquid chromatography analysis revealed that big endothelin-1 was cleaved into several amino acid sites by CAP, but endothelin-1 was not converted from big endothelin-1. CAP cleaved big endothelin-1 at different sites when compared with that of other known aspartic proteinases, and it suppressed endothelin-1 production through the degradation of big endothelin-1. CAP may break homeostatic mechanism of endothelin-1 in Candida albicans infectious lesions.
