Figure. Deduced amino acid sequence of PSE-1 (A), and OXA-2 (B) related enzymes that could be detected by polymerase chain reaction. Amino acids in boldface correspond to the regions of the primers. Dots indicate identical amino acids, and dashes indicated omitted regions with identical amino acids. Numbers correspond to amino acid position. Sequences obtained are underlined. GenBank accession no. of sequences are: PSE-1: Q03170, PSE-4: P16897, PSE-5: AAG23870, CARB-3: P37322, CARB-8: AAM92465, Proteus pCS229 blaP: JS0755, OXA-2: CAA30246, OXA-3: AAC41449, OXA-15: AAB05874, OXA-21: CAA71699, and OXA-32: AAK58418.
