Crystal Structure of RNA 3'-Terminal Phosphate Cyclase, a Ubiquitous Enzyme with Unusual Topology Structure, 8:13-, 2000 Cited by PubMed Abstract: RNA cyclases are a family of RNA-modifying enzymes that are conserved in eucarya, bacteria and archaea. They catalyze the ATP-dependent conversion of the 3'-phosphate to the 2',3'-cyclic phosphodiester at the end of RNA, in a reaction involving formation of the covalent AMP-cyclase intermediate. These enzymes might be responsible for production of the cyclic phosphate RNA ends that are known to be required by many RNA ligases in both prokaryotes and eukaryotes.
