This domain has no ligase activity, however together with the N-terminal domain they bind to double-stranded DNA consistent with the idea that the DNA-binding site is between the domains in the intact protein. Furthermore, although the fold of domain 2 is very similar to a number of other proteins that bind single-stranded DNA, this domain does not bind to single-stranded DNA but instead has a high affinity for double-stranded DNA [1].
