FIG. 2.

Schematic diagram showing insertion of Tn917 into Tn916 in S. pneumoniae. Relevant open reading frames (orfs) and restriction endonuclease sites are indicated. Numbers indicate nucleotide numbers based on GenBank sequences of Tn917 and Tn916. Location and the 5′ to 3′ direction of IPCR primers are indicated under the schematic for Tn917. Tn917 was inserted into orf9 at base 14525 in the published sequence of Tn916.
