Usage

It is demonstrated that the res-xre locus from Photorhabdus luminescens and other bacterial species function as bona fide TA modules in Escherichia coli.

It was shown that a RES toxin encoded by the α‐proteobacterium, Sinorhizobium meliloti, is toxic when expressed in Escherichia coli and can be counteracted by its cognate Xre antitoxin.

RES toxin from several bacterial species reversibly inhibits cell growth in E. coli, and that expression of the Xre antitoxin neutralizes this toxicity. However, the cellular function of the RES toxin when activated, as well as structure and the antitoxic mechanism of the Xre antitoxin, remain unknown.
