SfiI  (5064)
1 site

BstEII  (1252)
1 site

Sticky ends from different BstEII sites may not be compatible.
BstEII is typically used at 60°C, but is 50% active at 37°C.
Bpu10I  (1455)
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.
