T. Kimura et al., STRUCTURAL RELATIONSHIPS AMONG KILLER TOXINS SECRETED FROM THE KILLERSTRAINS OF THE GENUS WILLIOPSIS, Journal of fermentation and bioengineering, 80(1), 1995, pp. 85-87
The structural relationships among the killer toxins secreted from the
genus Williopsis were revealed by genomic Southern blot analysis and
immunoblot analysis. Killer toxins of W. mrakii and W. saturnus showed
structural similarities. However, killer toxins of W. beijericnkii an
d W. californica did not show any structural similarities although the
y had similar killer spectra to those of W. mrakii and W. saturnus.
