The K1 toxin of Saccharomyces cerevisiae kills spheroplasts of many yeast species
1989
Zhu, H. | Bussey, H.
The Saccharomyces cerevisiae K1 toxin killed spheroplasts from the genera Candida, Kluyveromyces, and Schwanniomyces. Cells of these organisms were toxin insensitive. The toxin bound poorly to Kluyveromyces lactis cells. In contrast, Candida albicans bound the toxin to an extent similar to that seen with S. cerevisiae. Thus, wall receptors can define toxin specificity and are necessary but not sufficient for toxin action on intact cells.
