QuickBLASTP is an accelerated version of BLASTP that is very fast and works best if the target percent identity is 50% or more. 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.

2022年2月28日 · BLAST Results. Analyzing the results of a BLAST search, while similar, will depend on whether the original search was for a nucleotide or amino acid sequence. Looking at the section "Sequences producing significant alignments" we see:

2025年3月17日 · 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.

Learn how to interpret BLAST results ; Understand the meaning of identity, coverage, e-value, and bitscore metrics; Keypoints¶ Interpreting the results of BLAST alignments requires thought and attention

Summarize BLAST results by parsing output file with a BioPerl script. 4. Run BLASTN search. 5. Plot data in R. Identifying and aligning similar DNA and protein sequences is one of the most common tasks in computational biology, and BLAST (Basic Local Alignment Search Tool) still represents one of the most widely used and effective tools.

UniProtKB, UniRef and UniParc results pages: directly from search results by selecting the results of interest and then selecting BLAST in the ‘tools’ dropdown menu. UniProtKB entry page: in the sequences section you can BLAST isoforms of a specific protein entry. You can submit sequences in multiple ways:

2008年6月23日 · The following example shows how to display the results of a BLAST search using a custom output format. The tabular output format with comments is used, but only the query accession, subject accession, evalue, query start, query stop, subject start, and subject stop are requested.

2022年2月28日 · 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 Or, you can run BLASTP directly from the RefSeq protein record as in the previous examples:

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.
