==Crystal Structure of Lyme Disease Variable Surface Antigen VlsE of Borrelia burgdorferi==
-
VlsE is an outer surface lipoprotein of Borrelia burgdorferi that, undergoes antigenic variation through an elaborate gene conversion, mechanism and is thought to play a major role in the immune response to, the Lyme disease borellia. The crystal structure of recombinant variant, protein VlsE1 at 2.3-A resolution reveals that the six variable regions, form loop structures that constitute most of the membrane distal surface, of VlsE, covering the predominantly alpha-helical, invariant regions of, the protein. The surface localization of the variable amino acid segments, appears to protect the conserved regions from interaction with antibodies, and hence may contribute to immune evasion.

[https://www.uniprot.org/uniprot/O06878_BORBG O06878_BORBG] The Vlp and Vsp proteins are antigenically distinct proteins, only one vlp or vsp gene is transcriptionally active at any one time. Switching between these genes is a mechanism of host immune response evasion.[RuleBase:RU363105]
