How to find HpaI sites in a sequence

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

Frequently asked questions

What sequence does HpaI cut?

HpaI recognizes GTTAAC (written 5' to 3') and cuts the top strand at GTT^AAC.

Does HpaI leave sticky or blunt ends?

Blunt ends, with no overhang.

How often does HpaI cut?

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