CdiA-CT regions in class 3 type-II proteins. (a) The different modules observed downstream of the PT-LPEN motifs are shown. Changes in the composition of the N-domain of the CT region are highlighted. SWR, switch regions at the N- and C-domain boundary are represented by ovals. (b) SWR sequences and immediately flanking residues of the upstream N- and downstream C-domains are shown. Predominant amino acids at each position of the SWR regions are indicated in capital letters. Sequences are coloured as in panel (a). Proteins marked by the prefix sei- and jun- were identified in Acinetobacter seifertii and Acinetobacter junii strains, respectively.
