title: A recA-ada hybrid gene inducible by DNA damage.
abstract: A damage-inducible expression vector was constructed in which the original recA structural gene was replaced by the protein-coding region of the ada gene. The O6-alkylguanine-DNA alkyltransferase encoded by the ada gene can be measured by a rapid and highly sensitive assay. The introduction of this construct into an appropriate host cell provides an effective bacterial assay for genotoxins.
