A predicted structure for the IKe gene V-VII sequence and β-galactosidase activities of deletion mutants (mutant 87 is, e.g., pSM7.87). The most stable secondary structure predicted for the gene VII initiation site (57) is shown on the left. The 5′→3′ deletion mutants generated from pSM7 are designated by the number of nucleotides in the IKe sequence remaining upstream from the initiator AUG. The AUG is shaded, and the SD sequence is indicated by a vertical line.
