blastp: Align two or more sequences using blastp-fast.

blastp

$ blastp -task blastp-fast -query ${query-fa} -subject ${subject-fa}

This command is using the BLASTP program to perform a protein-protein sequence similarity search. Here's what each part of the command does:

blastp: This is the executable command for the BLASTP program, which stands for Basic Local Alignment Search Tool for Proteins.
-task blastp-fast: This specifies the task or algorithm to be used by BLASTP. In this case, it is set to "blastp-fast," which suggests using a faster but potentially less sensitive search.
-query ${query-fa}: This option specifies the query sequence file to be used for the search. The file is identified by the variable ${query-fa}. Usually, this variable would be replaced with the actual file name or file path.
-subject ${subject-fa}: This option specifies the subject sequence file that will be searched against. Similar to the query sequence file, the subject file is identified by the variable ${subject-fa} and should be replaced with the actual file name or file path.

In summary, this command executes the BLASTP program using the fast algorithm and searches for similarities between the protein sequences in the query file and the subject file.
