This is a web version of the DePolymerase Predictor (DePP) tool described in Magill & Skvortsov (2023) BMC Bioinformatics paper. DePP is a machine learning tool that predicts the probability of a protein being a phage depolymerase. Please note that this web version should only be used for small scale projects. We advise you to use either the GUI or CLI version of DePP for large scale analyses.
