FIG. 2.

Nucleotide sequence of the 1,282-bp fragment of pRLT1 containing the VEB-1 β-lactamase coding region. The deduced amino acid sequence is designated in single-letter code below the nucleotide sequence. Conserved motifs for class A enzymes are underlined. The start and stop codons of the various genes are shown in boldface and underlined. RBS, putative ribosomal binding site of bla_VEB-1. The core sites (GTTRRRY) are double underlined, while the inverse core sites (RYYYAAC) are underscored with a dashed line. The composite 59-be’s are italicized.
