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.
PSORTb v3.0.3, released in February 2020, is the latest version. This mitigates a bug found in v3.0.2
when used to analyze archaeal cell envelopes when the view-results-via-email option was selected.
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. Web display mode is limited to the analysis of
approximately 100 proteins. For larger analyses, either
enter your email address in the form below (results of up
to 5000 per submission returned by email) or for even larger analyses we can help you or you can download the standalone version.
If you are interested in being notified about changes in the status of PSORTb, please subscribe to the
