The document provides a step-by-step guide on using the BLAST (Basic Local Alignment Search Tool) for protein sequence analysis, specifically via BLASTP. It outlines how to format input sequences in FASTA, input them into the BLAST tool, and interpret the results based on score matches. Several references and resources are included for further learning and guidance.

8. Protein Select Protease Homo sapiense

9. Click it

10. Click this FASTA format

11. This is our FASTA
format Sequence
& Click this to save
the FASTA format
In a Note pad &
copy the format
Open it & then
Select File

12. Types Select the p blast

13. Paste the FASTA sequence
Select reference protein

14. Select blastp
Click blast For result

18. The higher
the score ,
the better
the match
between
the query
and target
sequence
