FIG. 4.

Nucleotide sequence of the 2,177-bp SacI-EcoRI region encoding a cytochrome P450 (PipA), a putative ferredoxin (ORF1), and a putative glutamine synthetase (truncated ORF2′). The two sets of possible inverted repeats (underlined) in the putative promoter region of pipA, the putative ribosome binding sites ggagg (italic), and stop codons (asterisks) are indicated. The first 182 nucleotides of this sequence are identical to the end of the IS1096 insertion element (positions 2086 to 2268) except for one nucleotide: the base A, in position 2147 in IS1096, is missing. The GenBank accession number is AF102510. Bases shown in lowercase letters are noncoding sequences.
