How to find BssHII sites in a sequence

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

Frequently asked questions

What sequence does BssHII cut?

BssHII recognizes GCGCGC (written 5' to 3') and cuts the top strand at G^CGCGC.

Does BssHII leave sticky or blunt ends?

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

Which enzymes leave ends compatible with BssHII?

AscI and MluI. Their overhangs are the same, so the ends can be ligated to each other.

How often does BssHII cut?

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