BpmI  (2346)
1 site		 C T G G A G ( N ) 14 N N G A C C T C ( N ) 14
Efficient cleavage requires at least two copies of the BpmI recognition sequence.
Sticky ends from different BpmI sites may not be compatible.
After cleavage, BpmI can remain bound to DNA and alter its electrophoretic mobility.
BpmI quickly loses activity at 37°C.

The 1-base overhangs produced by AhdI may be hard to ligate.
Sticky ends from different AhdI sites may not be compatible.
RsrII  (1803)
1 site		 C G G W C C G G C C W G G C
Efficient cleavage requires at least two copies of the RsrII recognition sequence.
Sticky ends from different RsrII sites may not be compatible.
For full activity, add fresh DTT.

BsrGI is typically used at 37°C, but is even more active at 60°C.
BmgBI  (622)
1 site		 C A C G T C G T G C A G
This recognition sequence is asymmetric, so ligating blunt ends generated by BmgBI will not always regenerate a BmgBI site.
BstXI  (705)
1 site		 C C A N N N N N N T G G G G T N N N N N N A C C
Sticky ends from different BstXI sites may not be compatible.
