NAST -- a multiple sequence alignment server for comparative analysis of 16S rRNA genes

URL:
http://greengenes.lbl.gov/cgi-bin/nph-NAST_align.cgi
What you can do:
Compare 16s rRNA genes using multiple sequence alignment.
Highlights:
  • NAST sever is developed to efficiently align thousands of 16S rRNA genes via the NAST (Nearest Alignment Space Termination) algorithm for creating multiple sequence alignments.
  • Each user-submitted sequence is compared with Greengenes' 'Core Set', comprising approximately 10,000 aligned non-chimeric sequences representative of the currently recognized diversity among bacteria and archaea.
  • User sequences are oriented and paired with their closest match in the Core Set to serve as a template for inserting gap characters.
  • Non-16S data (sequence from vector or surrounding genomic regions) are conveniently removed in the returned alignment.
  • The ability to align and categorize large sequence sets using a simple interface has enabled researchers with various experience levels to obtain bacterial and archaeal community profiles.
