Abstract

Dominant-negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into mammalian cells new cell lines with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation or introduction of mutations by chemical mutagens. These methods are useful for generating novel and highly active antimicrobial molecules as well as superior antimicrobial agents from pre-existing chemicals. These methods are also useful for generating cell lines expressing novel antimicrobials that are useful for pharmaceutical manufacturing.
