Investigations on the role of cation-π interactions in active centers of superoxide dismutase

In this study, we have analysed the influence of cation?? interactions on stability and properties superoxide dismutase (SOD) active centres. The number formed by arginine is higher than lysine in cationic group, while those histidine are comparatively ? group. energy contribution resulting from most frequent was lower range strong hydrogen bonds. involving transition metal ions as cation more negative ?418.4 kJ mol-1. stabilization centres for these proteins showed that all residues involved were important locating one or such majority cation- evolutionarily conserved might a significant towards SOD proteins. results presented work can be very useful understanding to
