Fig. 1.

Maximum likelihood phylogenetic analysis of CptA and CptB. Maximum likelihood phylogenetic trees of 39 and 37 protein sequences of the candidate antitoxin (A) and toxin (B), respectively. Candidate Acinetobacter spp. antitoxins are highlighted in blue, while candidate toxins are highlighted in red. Their homologs in other species are represented in black. The analyses were conducted by the MEGA X software, where all positions with less than 95% site coverage were eliminated (i.e., fewer than 5% alignment gaps).
