Fig. 6From: F-CphI represents a new homing endonuclease family using the Endo VII catalytic motifStructures of the ββα-metal superfamily endonucleases. Protein structures of Hpy99I [36], Endo VII [26], I-HmuI [7], and I-PpoI [5] were obtained from previous studies. The structure model of F-CphI was generated based on Hpy99I structure using the online tool SWISS-MODEL (www.swissmodel.expasy.org/). The conserved active-site motif of each protein was colored orange and presented in the same orientationBack to article page
