The causative agent of Lyme disease, a multi-stage infection, is a family of spirochetes found in the guts of Ixodes ticks. The Variable Major Protein (VMP)-like sequence Expressed (VlsE) is the specific outer-surface lipoprotein that enables the spirochete to evade immune response through mechanisms of antigenic variation. In addition to inducing a strong immune response in the host, VlsE is useful in the serodiagnosis of Lyme disease (Eicken et al.).
Structural OverviewStructural Overview
VlsE is shown to be composed of four sub-units, each consisting of a variable domain flanked by two invariable domains (Liang). The variable domains themselves contain six variable regions (VR) interspersed amongst six invariable regions (IR). The IRs are embedded deep within the protein covered by alpha helical loops. They are shielded by the VRs.
