title: Method for identification of mutant glutathione S-transferases conferring enhanced resistance to the anti-cancer drug chlorambucil.
abstract: We screened library of mutant glutathione S-transferases (GSTs) in Escherichia coli by successive treatments with anti-cancer drug chlorambucil and identified mutant GSTs that conferred enhanced resistance to host against chlorambucil compared with wild-type GST. This study provides a method to develop enzymes with improved efficiency of detoxification against cytotoxic substances.
