how can i search in p-blast against UNIPROT(not only swissprot) i need to search for one protein against UNIPROT in BLAST for a selected organism.
How can I do it? (SWSISSPROT+TREMBL)
THANKS!!
I don't know of any online tool enabling a search against TrEMBL. You probably will have to set up your own local BLAST environment, roughly following these steps:


download blast+ - but there might be an easier way to install the software, depending on your operating system (e.g. on Ubuntu you can just sudo apt install ncbi-blast+)
download target databases
build local database


I hope this helps.
