Answers.Text: @flatley176 thank you for response. That answers what I can specify with -db. Unfortunately I'm not looking to blast against env_nr. I would like to blast against the website database using blast+ and specify this database:

  is there a way to specify this for a -remote blast using blast+
  
  thank you.

Answers.Text: I do not know how `Microbial proteins from nr` differs from the `env_nr` database. Page 3 of the BLAST manual (ftp://ftp.ncbi.nlm.nih.gov/pub/factsheets/HowTo_BLASTGuide.pdf) lists the available databases - the only reference to the word "microbial" is to the 16s rRNA. That said, I dug around a little more, and it appears there IS a solution - the database is called `Microbial_proteins`. Will update my answer.

Body: <p>I am attempting to run a BLAST search remotely using BLAST+.</p>
  
  <p>I can get search to work correctly at the command line with the following commands:</p>
  
  <pre><code>blastp -query proteins.fasta -remote -db nr -out proteins_nr.txt -outfmt 6 -evalue 1e-30
  </code></pre>
  
  <p>However, I would like to us the remote database titled "Microbial proteins from nr" which is what would be used for the microbial blast search accessing BLAST from the NCBI site.</p>
  
  <p>I'm struggling to find the correct code to access this database instead of just "nr".</p>
  
  <p>Is there a list with the codes of different databases?</p>

  I am attempting to run a BLAST search remotely using BLAST+.
  
  I can get search to work correctly at the command line with the following commands:
  
  ```
  blastp -query proteins.fasta -remote -db nr -out proteins_nr.txt -outfmt 6 -evalue 1e-30

  However, I would like to us the remote database titled "Microbial proteins from nr" which is what would be used for the microbial blast search accessing BLAST from the NCBI site.
  
  I'm struggling to find the correct code to access this database instead of just "nr".
  
  Is there a list with the codes of different databases?
  
  Thanks in advance

  I believe you're looking for `env_nr`? It's listed as such, under `Metagenomic proteins` in the blastp webpage. It appears that the word within brackets should be supplied alongside the `-db` parameter. A quick test with a dummy amino acid fasta file does turn up a result to a valid NCBI protein accession.
