Figure 2. Multiple sequence alignment of RepB sequences relevant to the respective protein of pSMA198.

The alignment was performed with ClustalW [23]. Double-headed arrows indicate positions of protein sequence signatures as determined by InterProScan [24], as follows: initiator Rep protein (dashed line), L. lactis RepB C-terminal (dotted line) and two consecutive winged helix-turn-helix transcription DNA-binding repressor (solid line).
