Pan proteomei This proteome is part of the Borrelia burgdorferi (strain ATCC 35210 / B31 / CIP 102532 / DSM 4680) pan proteome (fasta)

Borreliae, the causative agent of Lyme disease, are obligatorily bound to their host organisms for survival. It is a Spirochetes, a spiral-shaped bacterium. Highly specialized, motile, with two membranes, it lives primarily as an extracellular pathogen. During their life cycle they switch from the invertebrate host tick (Ixodes spec.) to various vertebrate hosts via a tick bite. It seems that Borellia have three indispensable components; a chromosome, a circular plasmid of approximately 26 kb and a linear plasmid of approximately 54 kb, each species can also contain many other plasmids. The range of vertebrates and invertebrates used as hosts is thought to be mediated by factors encoded mainly on a large number of different plasmids found in Borreliae genomes. These plasmids are characterized by their wealth of paralogous genes. It is thought that Borreliae plasmids are not stable and are frequently rearranged leading to differing plasmid content within a species. The chromosome is also involved in fission/fusion events, and the right end of the chromosome of B. burgdorferi strains is variable due to its ability to catch plasmids. During passage plasmids can be lost due to the lack of selection pressure, which can be accompanied by the inability of Borreliae to prosper in the host. It was first isolated in the early 1980s from the midgut of Ixodes ticks.
