Antigenic Variation in Lyme Disease Borreliae by Promiscuous Recombination of VMP-like Sequence Cassettes

TL;DR: An elaborate genetic system in the Lyme disease spirochete Borrelia burgdorferi that promotes extensive antigenic variation of a surface-exposed lipoprotein, VlsE, could potentially produce millions of antigenic variants in the mammalian host.
Journal ArticleDOI

Crystal structure of Lyme disease variable surface antigen VlsE of Borrelia burgdorferi.

TL;DR: The crystal structure of recombinant variant protein VlsE1 at 2.3-Å resolution reveals that the six variable regions form loop structures that constitute most of the membrane distal surface of VLSE, covering the predominantly α-helical, invariant regions of the protein.
Journal ArticleDOI

Human antibody responses to VlsE antigenic variation protein of Borrelia burgdorferi

TL;DR: The results indicate that VlsE may be useful in the immunodiagnosis of Lyme disease and may offer greater specificity than ELISAs using whole B. burgdorferi as the antigen.
Journal ArticleDOI

Characterization of a manganese-dependent regulatory protein, TroR, from Treponema pallidum

TL;DR: It is proposed that TroR represents a unique regulatory system for controlling gene expression in T. pallidum that exists as a dimer in both its inactive and active states as indicated by chemical crosslinking experiments.
