Alignment of the amino acid sequences of the A. baumannii and E. coli XerC and XerD. Catalytic, conserved amino acids are highlighted in red. The motif II is indicated by a solid yellow box. The tripeptides that act as acceptor in the donor–acceptor interaction with the C-terminal end of the partner protein are highlighted inside a solid gray box. The N-terminal region is boxed. Amino acid sequences are from accession numbers NP_418256.1 (E. coli MG1655 XerC), NP_417370.1 (E. coli MG1655 XerD), [43], VCCO00000000 (A. baumannii A118 XerC and XerD) [44].
