Figure 1. Defective inositol deacylation of GPI-APs in BST1-deficient C. albicans strains.

Figure 1

(A) Flow diagram used to investigate the inositol deacylation of GPI anchored protein (Als1p) in C. albicans assessed by its sensitivity to bacterial phosphatidylinositol-specific phospholipase C (PI-PLC). (B) Sensitivity of Als1p from parent and bst1Δ/Δ mutant strains to PI-PLC. Purified HA-tagged Als1p were treated as specified in Fig. 1A. After phase separation, both aqueous (A) and detergent (D) phases of Als1p underwent immunoblotting using anti-HA tag antibody. (C) Sensitivity of mannoproteins from parent SN152, BST1-complemented, bst1Δ/Δ null mutant and BST1S202A mutant strains to PI-PLC. Cytoplasmic proteins from the detergent (D) phases were treated as specified in Fig. 1A. After phase separation, both aqueous (A) and detergent (D) phases of proteins underwent immunoblotting using 2.5 μg/ml peroxidase labeled-Con.
