== Function ==
[https://www.uniprot.org/uniprot/BMPD_BORBU BMPD_BORBU] Binds adenosine and inosine but not guanosine, xanthosine or ribose (PubMed:31988175). May be part of an ABC-type nucleoside uptake system involved in the purine salvage pathway (Probable) (PubMed:31988175). Other probable members of the ABC transporter system are substrate binding proteins BmpB, BmpA and BmpC (BB_0382, BB_0383 and BB_0384 respectively), ATP transporter RbsA and 2 permeases (BB_0677, BB_0678 and BB_0679 respectively) (Probable) (PubMed:31988175).<ref>PMID:31988175</ref> <ref>PMID:31988175</ref>

== Publication Abstract from PubMed ==
Borrelia burgdorferi sensu lato (sl), the causative agent of the tick-borne Lyme borreliosis (LB), has a limited metabolic capacity and needs to acquire nutrients, such as amino acids, fatty acids, and nucleic acids, from the host environment. Using X-ray crystallography, liquid chromatography-mass spectrometry, microscale thermophoresis, and cellular localization studies, we show that Basic membrane protein D (BmpD) is a periplasmic substrate-binding protein of an ABC transporter system binding to purine nucleosides. Nucleosides are essential for bacterial survival in the host organism and these studies suggest a key role for BmpD in the purine salvage pathway of B. burgdorferi sl. As B. burgdorferi sl lacks the enzymes required for de novo purine synthesis, BmpD may play a vital role in ensuring access to the purines needed for sustaining an infection in the host. Further, we show that although human LB patients develop anti-BmpD antibodies, immunization of mice with BmpD does not confer protection against B. burgdorferi sl infection.
