摘要：

Plasmids containing DNA segments from the attachment region of phage HP1 were constructed and tested for the ability to replace the phage attachment site substrate in site-specific recombination reactions. The distance separating the boundaries of the functional site was 418 bp. Replacements within the 11-residue segment 5'-GGCGGTTATCG at the left boundary or within the 12-residue segment 5'-GGATTTTTTGAA at the right boundary abolished substrate activity. A segment of the 418-residue sequence preserves the integrity of an operon of three Haemophilus influenzae tRNA genes after HP1 insertion within the coding sequence.
