ABPDB: A Database of Antibacterial Peptides

Antibacterial peptides (ABPs) are a promising strategy to combat antimicrobial resistance. We constructed a comprehensive database named AntiBacterial Peptides DataBase (ABPDB) by collecting and integrating existing ABP databases. Specifically, ABPDB includes 4,872 ABPs and their sequence information, activity information, physicochemical properties and structural information. Three-dimensional structures of ABPs were predicted using AlphaFold2. In addition, we provided a service that allows users to find peptides that are structurally similar to a specific peptide.
