    Protein Summary

    This is a member of DUF820. It shares similar structure with 1wdj, a possible nuclease (rmsd 2.0A for 163 aligned Ca, 17% seq id) [Ref]. However, not all residues near the putative nuclease active are conserved (D80/Q45/E110/L112 vs DExEK). It is also homologous to 3ijm (MCSG) with rmsd 2.2A for 119 Ca, 12% seq id.


    This family of putative nucleases are highly abundant in cyanobacteria.
