FIG. 1.

Physical map of B. burgdorferi and B. hermsii recA genes and flanking regions. The numbers in parentheses are the numbers of nucleotides between ORFs, the numbers below the map are the lengths (in kilobases), and the arrows indicate the direction of transcription. The solid lines represent the complete gene sequence, while the dashed lines represent partial sequences. The approximate extent of the B. burgdorferi recA probe used for library screening is shown. The partial sequence of the BB0130 ORF of B. hermsii is homologous to ORF BB0130 of B. burgdorferi.
