FIG. 1.

Nucleotide sequence alignment of the replication regions of pSK1, pI9789::Tn552, and pSK41. The pSK41 sequence shown corresponds to nt 12991 to 14216 of GenBank entry AF051917. Nucleotides present in two or more sequences at any one position are shaded, and insertions or deletions are denoted by dashes. The nucleotide sequences are numbered on the right. Translation start and stop codons of the indicated genes (outlined) are boxed. Directly repeated sequences are indicated by arrows, whereas inverted repeats are shown by half arrows.
