How to find AvrII sites in a sequence

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

Frequently asked questions

What sequence does AvrII cut?

AvrII recognizes CCTAGG (written 5' to 3') and cuts the top strand at C^CTAGG.

Does AvrII leave sticky or blunt ends?

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

Which enzymes leave ends compatible with AvrII?

NheI, SpeI and XbaI. Their overhangs are the same, so the ends can be ligated to each other.

How often does AvrII cut?

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