Comparative view on the CLD and TMD of HlyB and RtxB. Basic residues in the CLD (a) and hydrophobic residues in the TMD (b) of HlyB, which are involved in interactions with HlyD, are marked in yellow14. The respective residues in RtxB are highlighted as bold letters. A pairwise sequence alignment was performed using the GGSEARCH2SEQ tool38.
