Welcome to BSepDB!

BSepDB (Bacterial Selenoprotein Database) serves as a comprehensive resource repository for selenoprotein genes that have been detected in bacteria. Selenoproteins, which are proteins containing the rare amino acid selenocysteine (Sec, U), play crucial roles in various biological processes, and understanding their distribution and function in different bacterial species is of significant scientific interest.

The current version of BSepDB encompasses 57,922 selenoprotein entries (belonging to 112 families/subfamilies) derived from 16,649 distinct bacterial organisms, spanning across 88 different taxonomic clades (phylum, class, and/or order levels).

The BSepDB team is dedicated to continually expanding and enriching this resource. As new selenoprotein genes are discovered in unexplored bacterial genomes, they will be promptly gathered, rigorously validated, and deposited into the BSepDB repository. This ongoing effort ensures BSepDB stays a leading platform of selenoprotein research, offering researchers the latest and most comprehensive bacterial selenoprotein data.
