How to find BsiWI sites in a sequence

  1. Paste a DNA sequence or FASTA record into the box above. BsiWI 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 BsiWI cut with its position. Copy or download the output below it.

Frequently asked questions

What sequence does BsiWI cut?

BsiWI recognizes CGTACG (written 5' to 3') and cuts the top strand at C^GTACG.

Does BsiWI leave sticky or blunt ends?

Sticky ends: a 4-base 5' overhang (GTAC).

Which enzymes leave ends compatible with BsiWI?

BsrGI. Their overhangs are the same, so the ends can be ligated to each other.

How often does BsiWI cut?

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