How to find BstBI sites in a sequence

  1. Paste a DNA sequence or FASTA record into the box above. BstBI is already entered under Only these enzymes.
  2. Tick Circular DNA for a plasmid, so a site that spans the end and the start is found.
  3. The map marks each BstBI cut with its position. Copy or download the output below it.

Frequently asked questions

What sequence does BstBI cut?

BstBI recognizes TTCGAA (written 5' to 3') and cuts the top strand at TT^CGAA.

Does BstBI leave sticky or blunt ends?

Sticky ends: a 2-base 5' overhang (CG).

Which enzymes leave ends compatible with BstBI?

ClaI, MspI and TaqI. Their overhangs are the same, so the ends can be ligated to each other.

How often does BstBI cut?

A site like TTCGAA turns up about once every 4,096 bp in random DNA. Real sequences vary, so check yours above.
