Membrane-mediated killing of Saccharomyces cerevisiae by glycoproteins from Torulopsis glabrata.

RESUMO
Cell-free supernatants from cultures of Torulopsis glabrata contained glycoprotein toxins that killed sensitive and killer strains of Saccharomyces cerevisiae with single-hit kinetics. Growing S. cerevisiae treated with the toxins showed a leakage of cellular potassium, partial dissipation of the adenosine triphosphate pool, and a coordinate shutdown of macromolecular synthesis. These pool efflux-stimulating toxins have been partially purified and at least three toxic glycoproteins have been separated. Pool efflux-stimulating toxin activity was stable from pH 3 through 7, though killing was maximal close to pH 4.
