Abstract:
Killer toxin from Saccharomyces cerevisiae SK was isolated by ultrafiltration of culture supernatants and purified by poly(ethylene glycol). The toxin migrates as one single protein band on SDS-PAGE and its molecular weight is 15 kD. The SK toxin has the greatest lethal effect on the sensitive yeast strain in the lat-lag phase. Extraction and purification of killer heretity factor(dsRNA) from SK found that M-dsRNA plasmid and L-dsRNA plasmid have different molecular lengths being 1.7 kb and 4.0 kb.
