Molecular Tour
Burkholderia pseudomallei is a rod-shaped, motile, flagellated, soil-dwelling gram-negative proteobacterium of the Burkholderiaceae family that thrives in tropical and subtropical regions. B. pseudomallei causes melioidosis, a deadly emerging opportunistic infection mainly of the immunocompromised. B. pseudomallei is transmitted through open wounds, contact with contaminated soil and water, ingestion, or inhalation, and is also a potential biological warfare agent. The Seattle Structural Genomics Center for Infectious Disease (SSGCID) has determined and solved X-ray structures of a potential drug target betaine aldehyde dehydrogenase (BADH) from B. pseudomallei (BpBADH). The structures are similar to that of BADH from Pseudomonas aeruginosa (PaBADH). PaBADH is inhibited by the drug disulfiram which is an approved drug. Our preliminary analysis could facilitate drug repurposing studies for melioidosis. This project is an educational collaboration between the SSGCID and Hampton University. The SSGCID consortium is directed by Dr. Peter Myler (principal investigator) and comprises many different scientists working at multiple centers towards determining the three-dimensional structures of proteins from biodefense organisms and emerging infectious diseases. Dylan K. Beard was part of a pilot Hampton University Chemistry Education and Mentorship Course-based undergraduate research (HU-ChEM CURES) funded by the NIGMS.
