Protein sequence identity
WebbSequence identity values from multiple sequence alignments are more reliable. Clustal is a program for generating multiple sequence alignments . SIAS is simple and good but you … WebbPSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run. PHI-BLAST performs the search but limits alignments to those that match a pattern in the query. DELTA-BLAST constructs a PSSM using the results of a Conserved Domain Database search and searches a sequence database.
