| Abstract: | Down regulation of the adaptive response to alkylation damage in Escherichia coli has been proposed to occur by proteolytic cleavage of the regulatory Ada protein. In this paper, it is shown that proteolysis of the Ada protein as observed in cell extracts is caused by the ompT gene product. This protease, however, was not involved in switching off the adaptive response in vivo. |
