Abstract

Colicin Ia can be cleaved by isolated outer membranes prepared from sensitive and resistant (lacking the colicin Ia receptor) strains of Escherichia coli. Both active and heat-denatured colicin Ia are extensively fragmented. Such proteolysis does not occur when colicin Ia is added to whole sensitive or resistant cells. These results demonstrate that cleavage of colicin Ia is not mediated by its outer membrane receptor.
