PanKB: An interactive microbial pangenome knowledgebase for research, biotechnological innovation, and knowledge mining

Abstract

AbstractThe exponential growth of microbial genome data presents unprecedented opportunities for mining the potential of microorganisms. The burgeoning field of pangenomics offers a framework for extracting insights from this big biological data. Recent advances in microbial pangenomic research have generated substantial data and literature, yielding valuable knowledge across diverse microbial species. PanKB (pankb.org), a knowledgebase designed for microbial pangenomics research and biotechnological applications, was built to capitalize on this wealth of information. PanKB currently includes 51 pangenomes on 8 industrially relevant microbial families, comprising 8, 402 genomes, over 500, 000 genes, and over 7M mutations. To describe this data, PanKB implements four main components: 1) Interactive pangenomic analytics to facilitate exploration, intuition, and potential discoveries; 2) Alleleomic analytics, a pangenomic- scale analysis of variants, providing insights into intra-species sequence variation and potential mutations for applications; 3) A global search function enabling broad and deep investigations across pangenomes to power research and bioengineering workflows; 4) A bibliome of 833 open- access pangenomic papers and an interface with an LLM that can answer in-depth questions using their knowledge. PanKB empowers researchers and bioengineers to harness the full potential of microbial pangenomics and serves as a valuable resource bridging the gap between pangenomic data and practical applications.Graphical Abstract
