Arrangement of the approximately 10 kb vls locus in B. burgdorferi located near the right telomere of linear plasmid 28-1. The directions of coding or expression are shown with horizontal arrows. Box 1 represents the expressed gene while boxes 2 through 16 represent silent gene cassettes. Figure modified from Zhang et al. (21).
