How to find SmaI sites in a sequence

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

Frequently asked questions

What sequence does SmaI cut?

SmaI recognizes CCCGGG (written 5' to 3') and cuts the top strand at CCC^GGG.

Does SmaI leave sticky or blunt ends?

Blunt ends, with no overhang.

How often does SmaI cut?

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