The bacteriophage P2 OLD protein, which has DNase as well as RNase activity [1,2] consists of an N-terminal ABC-type ATPase domain and a C-terminal Toprim domain. The nuclease activity of OLD is stimulated by ATP, though the ATPase activity is not DNA-dependent. The TOPRIM domain has two conserved motifs, one of which centres at a conserved glutamate and the other one at two conserved aspartates (DxD). The conserved glutamate may act as a general acid in strand cleavage by nucleases. The DXD motif may co-ordinate Mg2+, a cofactor required for full catalytic function [3].
