Multiple sequence alignments of bacteriocin ABC transporters. Cysteine and histidine, which are part of the putative active site of the peptidase family C39B, as well as glutamine, which contributes to the oxyanion pore in other cysteine protease families, are marked with * and indicated in yellow. The ATP-binding site and ABC transporter signature motifs are indicated in yellow and marked with †and #, respectively. The alignment was carried out using the program Genetyx-Mac 16.0.9. C. divergens: ATP-dependent transporter of Carnobacterium divergens, L. lactis: Lactococcin-A transport/processing ATP-binding protein LcnC of Lactococcus lactis subsp. lactis, L. mesenteroides: Mesentericin-Y105 transport/processing ATP-binding protein MesD of Leuconostoc mesenteroides, P. acidilactici: Pediocin PA-1 transport/processing ATP-binding protein PedD of Pediococcus acidilactici, TDE_0425: tepA1, TDE_0719: tepA2, TDE_2431: tepA3
