Borrelia burgdorferi genes containing a perfect direct repeat sequence (TAAATTAAAT) in their putative promoter regions.

1, Candidate genes were identified by searching B. burgdorferi B31 genome using “Regulatory Sequence Analysis Tools”. Gene promoter was defined as the region encompassing sequences from -400 to +50 (relative to a putative translation start ATG).2, Four flanking nucleotides are also shown.
