[BiO BB] How to find the same proteins?

[Pankaj]

For this u can go to NCBI BLAST page and go to BLASTP. There u can paste ur
sequence and select PDB as the database to query. Just click on BLAST and u
get all seq similar to ur sequence. Filter out the results to find PDB ids
>99% similar to ur protein.
Sine u have 200 proteins u can download NCBI database and run local BLAST also.
