FIG. 3.

Nucleotide sequences of left and right IPCR fragments, Tn916 and Tn917, respectively. The beginnings and ends of orf6 and orf9 are as indicated. Uppercase letters indicate Tn916-derived sequences; lowercase letters indicate Tn917-derived sequences. Numbers at the right of the Tn916 and Tn917 sequences indicate nucleotide numbers based on GenBank sequences. The AvaI sites at the left and right termini of Tn917 are underlined. The positions of primers L2 and R2 are indicated by arrows below the sequence of Tn917. The 5-base target site duplication is boxed. (A) Sequence of the Tn917 left terminal junction fragment. (B) Sequence of the Tn917 right terminal junction.
