Partial nucleotide sequence (nt 1-1842) of chloramphenicol resistance plasmid pKH7 has been reported previously and residual nucleotide sequence (nt 1843-4118) of pKH7 was determined and then the complete nucleotide sequence of pKH7 was obtained. pKH7 consists of 4118 bp and has three ORFs. Besides Rep and CAT proteins described in previous paper, Pre protein which mediates site-specific recombination in Staphylococcus aureus was found to be on pKH7. R $S_{A}$, a site-specific recombination site of Pre protein, and palA, a specific lagging-strand conversion signal, was also found in pKH7. Amino acid sequence of Pre protein of pKH7 was compared with those of other antibiotic resistant Staphylococcus aureus plasmids.s.
