Isolation, purification, and characterization of a killer protein from Schwanniomyces occidentalis.

Applied and environmental microbiology - 1 Dec 2000

Chen W B, Han Y F, Jong S C, Chang S C

Abstract excerpt

The yeast Schwanniomyces occidentalis produces a killer toxin lethal to sensitive strains of Saccharomyces cerevisiae. Killer activity is lost after pepsin and papain treatment, suggesting that the toxin is a protein. We purified the killer protein and found that it was composed of two subunits with molecular masses of approximately 7.4 and 4.9 kDa, respectively, but was not detectable with periodic acid-Schiff...
