Characterization of Trp(+) reversions in Escherichia coli strain WP2uvrA.

Mutagenesis - 1 Jul 2002

Ohta Toshihiro, Tokishita Shin-ichi, Tsunoi Rumi, Ohmae Satoru, Yamagata Hideo

Abstract excerpt

The Escherichia coli strain WP2uvrA is widely used in general mutagenicity screening tests because of its high sensitivity to many kinds of mutagens and it serves as a supplement to the standard Salmonella typhimurium tester strains. In contrast to Salmonella His(+) revertants, E.coli Trp(+) revertants have not been characterized at the molecular level. In this study we found that in the trpE65 allele of WP2uvrA...
