DNase with activity at alkaline pH?

[Roger Graham]

Dear Netters :

I would like to enzymatically cleave plasmid DNA at pH 9-10; specifically I
would like to show protection/cleavage of my DNA from "DNaseI"-type
activity in the presence/absence of my complex. Unfortunately, neutral pH
dissociates my complex. Any suggestions for a candidate nuclease ?

Thanx,
