Fig. 7From: Molecular diversity of extended-spectrum β-lactamases and carbapenemases, and antimicrobial resistanceA phylogenetic tree of the class D β-lactamase OXA family (oxiacillinase). A phylogenetic tree of the OXA types of β-lactamases. OXA-10, OXA-11, and OXA-15 are recognized as extended-spectrum cephalosporinases, whereas OXA-23 and OXA-48 are recognized as carbapenem-hydrolyzing class D β-lactamases (CHDLs). Based on the primary sequences, the tree was generated using Clustal Omega [32,33,34] of GenomeNet at Kyoto University Bioinformatics Center (https://www.genome.jp/tools-bin/clustalw)Back to article page
