1. Maximum likelihood amino acid tree of the OXA-type β-lactamases found in Acinetobacter species.
Maximum likelihood amino acid tree of the OXA-type β-lactamases found in Acinetobacter species. For enzymes for which a designation was not available, the species and strain designation are used instead. Due to its large size, the OXA-51 enzyme group has been collapsed so that the other enzyme groups can be more easily seen. Relationships between the OXA-51-like enzymes are shown in Fig. 5. The tree was implemented in SeaView version (172) with PhyML using a Le and Gascuel (LG) model (173). Support was estimated by using approximate likelihood ratio tests, the results of which label the branches. The tree was visualized by using FigTree version ( and is midpoint rooted.
