Searching NCBI Databases Using Entrez

Copy the query translation of the previous search Go to the GQuery start page Paste the query into the GQuery search box Change into Click Search You only see results for the Nucleotide database. So you search for protease NOT hiv [Organism]. You can use the same syntax in the GQuery search if you want to yquery all databases for sequences in this length range.
