Can we exploit past phage infection events (prophages) to decipher the specificity of phage receptor-binding proteins such as depolymerases?🔎 Happy to share our recent work at @natcomms.nature.com 🔽 #microsky #phagesky

Unlocking data in Klebsiella lysogens to predict capsular type-specificity of phage depolymerases - Nature Communications
Here, the authors exploit the genetic information encoded in Klebsiella prophages to model the interplay between bacteria, prophages, and their depolymerases, using a directed acyclic graph-model and a sequence clustering-based model.
