The proteolytic regulation of toxin–antitoxin (TA) systems has been well studied in Escherichia coli but remains unclear in other bacteria. A chromosomal gene pair ssr1114/slr0664, named relNEs, of Synechocystis sp. PCC 6803 forms a TA system belonging to rel family. Here, we used E. coli strain BL21 (DE3) as a host to characterize the proteolytic regulation of relNEs. The proteases of this strain could not degrade the antitoxin RelN, and the ectopic production of the ATP-dependant protease… CONTINUE READING
