BLAST basic local alignment search tool is a tool for comparing primary biological sequence information such as the amino-acid sequences of proteins. A BLAST search enables a researcher to compare a subject protein called a query with a database of sequences, and identify database sequences that resemble the query sequence above a certain threshold. Figure 38 Figure 38 The Blast input page interactive image. Jobs have unique identifiers, which depending on the job type can be used in queries e.

Federal government websites often end in. The site is secure. Enter coordinates for a subrange of the query sequence. Sequence coordinates are from 1 to the sequence length. The range includes the residue at the To coordinate. Use the browse button to upload a file from your local disk. The file may contain a single sequence or a list of sequences. Enter one or more queries in the top text box and one or more subject sequences in the lower text box.

These options allow you to select sequence annotations like domains, sites, etc. The overview table presents color coded results that are ordered by identity by default. The lower the e-value, the more likely the match is to be significant. You will see a search results page as shown in Figure 4. A list of optional settings for your Blast search can be found in the help section. An auto-complete functionality will help you with this. BLAST sequence similarity searching. The detailed alignment table shows the alignment graphically with the query shown in black and the subject hit color coded to reflect identity following the same scale as the overview table. As a library, NLM provides access to scientific literature. You can select entries in your alignment table by clicking on the checkboxes to their left and then submit them to the Blast tool, the align tool or add them to your basket. This unit provides three basic protocols, three alternate protocols and two supporting protocols for using UniProt tools. The order can be changed to view the diagram sorted by E Value or Bit Score.

The program compares nucleotide or protein sequences and calculates the statistical significance of matches.

In all cases, those matches need to be verified manually. You will see the Align input page as shown in Figure 8. This tool runs the Clustal Omega algorithm to find areas of similarity in the entries being aligned. Figure 4. The expectation value E threshold is a statistical measure of the number of expected matches in a random database. This is optional.

This can be used to infer functional and evolutionary relationships between sequences as well as to help identify members of gene families. The results page provides 1 a left hand panel with filters and options to view the results arranged by taxonomy or view the raw alignments, 2 an overview graphical list on top of the page and 3 a detailed table of alignments underneath that. Each row is colored using a heat map scale with red reflecting the closest identity to the query sequence and blue reflecting the least identity.
