PSI Protein Classifier
open-in-new
<p>PSI Protein Classifier is a program generalizing the results of both successive and independent <a href="/facts/Iteration/AMc1p7BL">iterations</a> of the <a href="/facts/PSI-BLAST/uWufGxFH">PSI-BLAST</a> program. PSI Protein Classifier determines belonging of the found by PSI-BLAST <a href="/facts/Proteins/Jxmagu3E">proteins</a> to the known <a href="/facts/Protein_family/EHt5xwCA">families</a>. The unclassified proteins are grouped according to similarity. PSI Protein Classifier allows to measure <a href="/facts/Evolution/Hj0qAaBk">evolutionary</a> distances between families of <a href="/facts/Homology_(biology)/muctKlyT">homologous</a> proteins by the number of PSI-BLAST iterations. </p>
