FIG. 2.

Nucleotide sequence of the 1,429-bp PCR product encoding bec and the flanking regions. The deduced amino acid sequence is shown in one-letter code. S/D, putative Shine-Dalgarno sequence. The asterisk indicates a stop codon. The shading indicates an oligonucleotide binding site. The sequence from −35 to −10 is a putative ς⁷⁰ recognition sequence. The sequence from −24 to −10 is a putative ς⁵⁴ recognition sequence. The nucleotide sequence upstream of the PstI recognition sequence was located on the 0.9-kbp PstI fragment.
