Alkaline phosphatase at the cell wall of the yeast phase ofParacoccidioides brasiliensis

Abstract: The activity of alkaline phosphatase demonstrated by histochemical techniques was shown at the cell wall of the yeast form of Paracoccidioides brasiliensis at 3, 6, and 9 days of culture. The results showed a very active deposition at the cell wall as early as 9 days of culture of the fungus which made us think an inactive salt precipitate was also present.

“…We reported on a mitochondrial heat-shock chaperone Mdj1 labeled at the P. brasiliensis yeast cell wall (Batista et al, 2006, 2007), which is the preferential site in fully formed mycelia (Dourado et al, unpublished). Alkaline phosphatase activity on the cell wall was demonstrated by histochemical techniques in P. brasiliensis yeast phase (Campo-Aasen and Albornoz, 1994). A secreted 75-kDa protein with phosphatase activity was identified by confocal microscopy and flow cytometry on the cell surface, preferentially at the budding site of P. brasiliensis (Xander et al, 2007).…”

“…Protein phosphatases may exist in soluble [4,12] or secreted forms [1320], or even remain attached to the outer surface of the inner membrane [2123] or the cell wall [24,25]. In this context, the ectophosphatases are surface membrane-bound proteins whose active site faces the extracellular medium [2628].…”

“…In fungi, ectophosphatases have been described in a large number of species, including Saccharomyces cerevisiae [25], Sporothrix schenckii [32], Paracocciodiodes brasiliensis [24], Candida parapsilosis [33,34], Kluyveromyces marxianus [35], Aspergillus fumigatus [36], Fosencaea pedrosoi [37,38], Cryptococcus neoformans [39], Pseudallescheria boydii [40], Candida albicans [41], Rhinocladiella aquaspersa [42] and Metarhizium anisopliae [43]. It is noteworthy that this review focuses on medically relevant fungal species.…”
