BLASTN against Database page

Enter a nucleotide sequence in fasta format or just the sequence and perform a BLASTN query against the database.
This allows users to compare novel islands to the database with the aid of sequence comparison.
Default e-value is set but may be changed to increase stringency.

Results will be presented in the same page.
The e-value employed will be presented in the results box.
The Filter BLAST results option will navigate users to a new page where the result subject list may be filtered.
Hit subject islands with an asterisk (*) contain ribosomal proteins and may indicate a False Positive Prediction!.
Information regarding the BLASTN hit is presented in a tabular format with subject islands hyperlinked to allow inspection of the subject island with which a hit was found.
BLASTN visualization is possible through the BLASTN svg link.
