FIG. 4.

Sequence of the gpo-carB intercistronic region. The numbers refer to the sequences submitted to the database. The amino acids of the glutathione peroxidase and CPSase large subunit derived from the DNA sequence are shown. The translational start site of carB is indicated with double underscoring. The −10 and −35 sequences of the carB promoter are indicated with underscoring, and the first nucleotide to be transcribed is marked +1. The right and left stems of loops I, II, and III (Fig. 5) are shown.
