you can try the following databases

http://www.virusite.org/

https://viralzone.expasy.org/.

http://bioafrica.mrc.ac.za/rnavirusdb/

In addition if you try

http://insilico.ehu.es/PCR/index.php?mo=eukarya

upon processing you will find a section of a lot of viral genomes

GOOD LUCK

You directly download these refseq protein sequences using retrieve sequences(present in top right of webpage).

This link taken in to you in protein NCBI page. Click file radio button and download it in FASTA format. Do this for all three txid's. Then merge all FASTA file.

Finally use standalone blast for making database(makeblastdb) and blastx.

Hope this will help you.

go to NCBI....choose file type as "protein" n type ur protein name n search...will show list of proteins... select proteins of your interest and click "send to" option available on same page...choose destination ...click "file"... format ....choose FASTA n then create file... like this u can download all the proteins file of ur interest n do blastx.

Hey guys, thank you all!! every answer offered worked!
