Summary
DNA/RNA ligase superfamily
This superfamily contains both ATP-dependent and NAD dependent DNA ligase enzymes. The family also includes mRNA capping enzymes. The members of this clan were shown to be related by sequence in [1].
This clan contains 5 families and the total number of domains in the clan is 30800. The clan was built by A Bateman.

Structures
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
