Submit a Sequence to PSORTb version 3.0.2 new!

Based on a study last performed in 2010, PSORTb v3.0.2 is the most precise bacterial localization prediction tool available. PSORTb v3.0.2 has a number of improvements over PSORTb v2.0.4. Version 2 of PSORTb is maintained here.

You can currently submit one or more Gram-positive or Gram-negative bacterial sequences or archaeal sequences in FASTA format (?). Copy and paste your FASTA-formatted sequences into the textbox below or select a file containing your sequences to upload from your computer.

This is the most current version of the PSORTb program for bacterial protein subcellular localization prediction. PSORTb v3.0 now handles archaeal sequences as well as Gram-positive and Gram-negative bacterial sequences. Plus, it has several other improvements. Version 2 of PSORTb is maintained here (but we strongly recommend using version 3.0! ;-). If you are looking for a eukaryotic localization predictor, please visit psort.org to access other resources.
