SwaI  (37)

Bpu10I  (186)
1 site
C C T N A G C G G A N T C G

Cleavage may be enhanced when more than one copy of the Bpu10I recognition sequence is present.
This recognition sequence is asymmetric, so ligating sticky ends generated by Bpu10I will not always regenerate a Bpu10I site.
Sticky ends from different Bpu10I sites may not be compatible.
