Positive selection for colicin diversity in bacteria.

Molecular biology and evolution - 1 Sept 1993

Riley M A

Abstract excerpt

To examine the hypothesis that colicin proteins are subject to diversity-enhancing selection, we studied the rates of synonymous, nonsynonymous, and intergenic nucleotide substitution in three pairs of closely related colicin clusters. The results indicate that the immunity gene and the immunity-binding domain of the colicin gene, which interact to provide specific immunity from the lethal action of the colicin...
