Genetic variability of Candida albicans Sap8 propeptide in isolates from different types of infection.

ABSTRACT: The secreted aspartic proteases (Saps) are among the most studied virulence determinants in Candida albicans. These proteins are translated as pre-pro-enzymes consisting of a signal sequence followed by a propeptide and the mature enzyme. The propeptides of secreted proteinases are important for the correct processing, folding/secretion of the mature enzyme. In this study, the DNA sequences of C. albicans Saps were screened and a microsatellite was identified in SAP8 propeptide region. The genetic variability of the repetitive region of Sap8 propeptide was determined in 108 C. albicans independent strains isolated from different types of infection: oral infection (OI), oral commensal (OC), vulvovaginal candidiasis (VVC), and bloodstream infections (BSI). Nine different propeptides for Sap8
