Abstract
The synthesis of the major outer surface proteins OspA and OspB in Borrelia burgdorferi varies among strains and during in vitro cultivation. We examined B. burgdorferi CA-11.2A for the presence of proteins that bind to the ospAB operon promoter region. Three major DNA-protein complexes were detected using a mobility shift assay; one of these complexes was due to sequence-specific binding. These proteins may be involved in the regulation of ospAB transcription and the pathogenesis of Lyme disease.
