Název v původním jazyce

Sulphite efflux pumps in Aspergillus fumigatus and dermatophytes

Popis výsledku v původním jazyce

Dermatophytes and other filamentous fungi excrete sulphite as a reducing agent during keratin degradation. In the presence of sulphite, cystine in keratin is directly cleaved to cysteine and S-sulphocysteine, and thereby, reduced proteins become accessible to hydrolysis by a variety of secreted endo- and exoproteases. A gene encoding a sulphite transporter in Aspergillus fumigatus (AfuSSU1), and orthologues in the dermatophytes Trichophyton rubrum and Arthroderma benhamiae (TruSSU1 and AbeSSU1, respectively), were identified by functional expression in Saccharomyces cerevisiae. Like the S. cerevisiae sulphite efflux pump Ssu1p, AfuSsu1p, TruSsu1p and AbeSsu1p belong to the tellurite-resistance/dicarboxylate transporter (TDT) family which includes the Escherichia coli tellurite transporter TehAp and the Schizosaccharomyces pombe malate transporter Mae1p. Seven genes in the A. fumigatus genome encode transporters of the TDT family. However, gene disruption of AfuSSU1 and of the two more
