a, b and c Structural validation of the DnMRE11 model using ProSA web tool. a ProSA overall Z score,9.5 is indicated in graph as black dot. A negative value of overall energy profile confirmed the reliable structural conformation of DnMRE11. b Energy profile of the DnMRE11 homology model. c Ramachandran plot of the DnMRE11 model showing 80 % of amino acid residues in the core region (dark gray)
