How to find SacI sites in a sequence

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

Frequently asked questions

What sequence does SacI cut?

SacI recognizes GAGCTC (written 5' to 3') and cuts the top strand at GAGCT^C.

Does SacI leave sticky or blunt ends?

Sticky ends: a 4-base 3' overhang (AGCT).

How often does SacI cut?

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