BlastP simply compares a protein query to a protein database. PSI-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.

The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
Feb 28, 2022 · BLASTP Example. This illustration shows how to search for a protein sequence using BLASTP. You can start from the NCBI BLAST home page: http://blast.ncbi.nlm.nih.gov/Blast.cgi

Large-scale protein sequence comparison is an important but compute-intensive task in molecular biology. BLASTP is the most popular tool for comparative analysis of protein sequences.
Click on the link indicated by “P” next to “Protein–protein BLAST (blastp)” to access the problem. It describes how to use blastp to determine the type of protein. For this purpose, we will choose the database containing the curated and annotated protein sequences, such as RefSeq or Swissprot. Use the query sequence provided in the ...
Overview of the BLASTP process. The query sequence EAGLES into broken into three-letter words or synonyms that are used as a search set against records in a protein or translated nucleotide database.
Jan 28, 2011 · The Basic Local Alignment Search Tool ( BLAST) is the most widely used sequence similarity tool. There are versions of BLAST that compare protein queries to protein databases, nucleotide queries to nucleotide databases, as well as versions that translate nucleotide queries or databases in all six frames and compare to protein databases or queries.
Jul 30, 2023 · The blastp is a command-line utility from the NCBI BLAST toolkit that is used for performing protein-protein sequence similarity searches using the BLAST algorithm. blastp compares a query protein sequence against a protein BLAST database to identify homologous protein sequences.
