P4P: Peptidomes for Phylogenies
This website is free and open to all users and there is no login requirement.
P4P (pronounced “pie for pie”) is a bioinformatics web service which has been conceived for bacterial strain classification based on peptide datasets. These peptide datasets are obtained from proteins by the in silico action of the three main human gut endoproteases (pepsin, trypsin and chemotrypsin). Peptides can be filtered by isolectric point, subcellular location, or amino acid length. DOI: 10.1093/nar/gkx389

Generate all NEXUS files you want. P4P allows you to specify the size of peptides, their subcellular localization or isoelectric points.
We use MrBayes to automatically generate bayesian trees for your nexus files. You can download or visualize them on our tool.
