FIG. 1.

The Tn1546 encoding vancomycin resistance. The sizes and positions of the genes are indicated. The genes are grouped into the categories Mobility, Regulation, Essential, and Accessory according to their importance for vancomycin resistance. The positions and names of the primers used for amplification of an internal area of vanX are indicated as is the size for the obtained amplicon. Sequences from position 8230 to 8240 for the G and T types are shown with the base pair variation underlined. The sequence for the G-type variation is from the first published sequence for strain BM4147.
