How to find Sau3AI sites in a sequence

  1. Paste a DNA sequence or FASTA record into the box above. Sau3AI 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 Sau3AI cut with its position. Copy or download the output below it.

Frequently asked questions

What sequence does Sau3AI cut?

Sau3AI recognizes GATC (written 5' to 3') and cuts the top strand at ^GATC.

Does Sau3AI leave sticky or blunt ends?

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

Which enzymes leave ends compatible with Sau3AI?

BamHI, BclI and BglII. Their overhangs are the same, so the ends can be ligated to each other.

How often does Sau3AI cut?

A site like GATC turns up about once every 256 bp in random DNA. Real sequences vary, so check yours above.
