Figure 1

Amino acid sequence alignments for three RelE toxin proteins and their cognate RelB antitoxin proteins.

Putative RelBE1sca (SCATT_20920-SCATT_20930) and RelBE2sca (SCATT_39280-SCATT_39270) pairs were identified on the S. cattleya DSM46488 chromosome while the well-documented RelBE module RelBEeco (b1564-b1563) is encoded by E. coli K-12 MG1655 chromosome. Conserved residues are shown in red and by boxed. The black triangle indicates the active sites of the E. coli toxin RelEeco while the underlined sequence indicates the RelBeco conserved motif interacting with RelEeco14,30. Secondary structures were predicted by using PSIPRED43.
