| Popis: | The H/A gene region of the bacteriophage S13 genome (map positions 4597 to 289) was analyzed for Escherichia coli RNA polymerase-binding sites by combined DNase I footprinting, exonuclease III analysis and DNA sequencing. Two high-affinity binding sites were identified, one corresponding to the A gene promoter at position 5384 to 56, overlapping the H/A intergenic region at position 1 to 63, the other at position 5171 to 5230, at the 3'-end of the H gene. A medium-affinity RNA polymerase binding site was mapped at position 4810 to 4850 in the middle of the H gene upstream of a low-affinity site at position 5280 to 5330. The studies complete footprinting analyses of the S13 genome from position 4597 to 2198 and in combination with previous studies on transcription provide definitive evidence on the position of the A gene promoter in S13 and the closely related phage psi X174. |
