NmeAIII  (6200)
1 site
G C C G A G ( N ) 18-19 N N C G G C T C ( N ) 18-19

Efficient cleavage requires at least two copies of the NmeAIII
recognition sequence.
Sticky ends from different NmeAIII sites may not be compatible.
For full activity, add fresh S-adenosylmethionine (SAM).
BpmI  (6122)
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.

long incubations.
BmgBI  (4167)
