Sequence alignment of ABC transporter containing the N-terminal peptidase domain. The amino acid sequence alignments of NukT, LctT, CvaB, LcnC, and ComA were performed using the ClustalW program. The conserved active sites in the peptidase domain are marked with asterisks. The conserved motifs in the ABD (Walker A, Walker B, H-loop) are indicated under the sequence. The mutation points in NukT are shown above the sequence.
