FIG. 1.

Local alignment of the bla_toho1 and bla_toho2 genes. Toho-1 starts at base 640 and Toho-2 starts at base 661, following the numbering system of Ma et al. (8). Six presumed bases, starting at position 676 of bla_toho2, were introduced. The protein alignment is deduced from the bla_toho1 gene and the bla_toho2 gene after introduction of the six bases. “ABL” represents Ambler’s numbering scheme for amino acids (2). ▾, putative bases. Note that the four codons “gc▾” code for glycine (Gly-217).
