FIG. 4.

Nucleotide sequence of katA and flanking regions. Shown is the 5′→3′ sequence of a 2,577-nucleotide segment of Y4Nal genomic DNA starting from the stop codon of a predicted glutamate dehydrogenase gene (GenBank accession no. AF162654). The predicted amino acid sequence of the katA product is also shown. The −35 and −10 promoter sequences and the Shine-Dalgarno sequence (SD) are boxed. The insertion sites for IS903φkan are shown by vertical arrows above the sequence. The nucleotides duplicated at the sites of IS903φkan insertions are also boxed. The 11-bp putative DNA uptake sequences are underlined. Inverted repeats are indicated by horizontal arrows above the sequence. Asterisks indicate nucleotide differences with respect to the Genome Sequence Project database. None of the differences result in a change of amino acid. The two HindIII sites present in the region are indicated above the sequence.
