BBE31 from the Lyme disease agent Borrelia burgdorferi, known to play an important role in successful colonization of the mammalian host, shows the a…

Abstract Lyme disease is a tick-borne infection caused by Borrelia burgdorferi sensu lato complex spirochetes. The spirochete is located in the gut of the tick; as the infected tick starts the blood meal, the spirochete must travel through the hemolymph to the salivary glands, where it can spread to and infect the new host organism. In this study, we determined the crystal structures of the key outer surface protein BBE31 from B. burgdorferi and its orthologous protein BSE31 (BSPA14S_RS05060 gene product) from B. spielmanii. BBE31 is known to be important for the transfer of B. burgdorferi from the gut to the hemolymph in the tick after a tick bite. While BBE31 exerts its function by intera…
Targeting Bacterial Sortase A with Covalent Inhibitors: 27 New Starting Points for Structure-Based Hit-to-Lead Optimization.

Because of its essential role as a bacterial virulence factor, enzyme sortase A (SrtA) has become an attractive target for the development of new antivirulence drugs against Gram-positive infections. Here we describe 27 compounds identified as covalent inhibitors of
Structural analysis of Borrelia burgdorferi periplasmic lipoprotein BB0365 involved in Lyme disease infection.
2019
The periplasmic lipoprotein BB0365 of the Lyme disease agent Borrelia burgdorferi is expressed throughout mammalian infection and is essential for all phases of Lyme disease infection; its function, however, remains unknown. In the current study, our structural analysis of BB0365 revealed the same structural fold as that found in the NqrC and RnfG subunits of the NADH:quinone and ferredoxin:NAD+ sodium-translocating oxidoreductase complexes, which points to a potential role for BB0365 as a component of the sodium pump. Additionally, BB0365 coordinated Zn2+ by the His51, His55, His140 residues, and the Zn2+ -binding site indicates that BB0365 could act as a potential metalloenzyme; therefore…
