Characterization of two genes, p11 and p5, on the Borrelia burgdorferi 49-kilo base linear plasmid

A putative operon encoding two Borrelia burgdorferi N40 genes, p11 and p5 was cloned and localized to the 49 kilobase linear plasmid. p11 encodes an 11 kDa protein and p5 encodes a 5 kDa protein. The first 88 nucleotides of p11 have 81% identity with orf5 on a circular plasmid from Borrelia afzelii strain Ip21, suggesting that homologues of these genes may be present in different regions of the B. burgdorferi genome.
