MutS2 protein of Pyrococcus furiosus has been cloned and over-expressed. Initial characterization reveals that PfuMutS2 possesses a thermostable ATPase activity and a thermostable, nonspecific DNA binding activity. However, PfuMutS2 does not have any detectable mismatch-specific DNA binding activity. It is the first in vitro characterization of an MutS2 family protein.
