RNA-guided endonucleases, once thought to be exclusive to prokaryotes, have been recently identified in eukaryotes and are called Fanzors. They are classified into two clades, Fanzor1 and Fanzor2. Here we present the cryo-electron microscopy structure of Acanthamoeba polyphaga mimivirus Fanzor2, revealing its omegaRNA architecture, active site and features involved in transposon-adjacent motif recognition. A comparison to Fanzor1 and TnpB structures highlights divergent evolutionary paths, advancing our understanding of RNA-guided endonucleases. | RNA-guided endonucleases, once thought to be exclusive to prokaryotes, have been recently identified in eukaryotes and are called Fanzors.
