CC -!- FUNCTION: Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic
CC phosphodiester at the end of RNA. The mechanism of action of the enzyme
CC occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer
CC of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of
CC the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to
CC produce the cyclic end product. The biological role of this enzyme is
CC unknown but it is likely to function in some aspects of cellular RNA
CC processing. {ECO:0000255|HAMAP-Rule:MF_00200}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 3'-end 3'-phospho-ribonucleotide-RNA + ATP = a 3'-end 2',3'-
CC cyclophospho-ribonucleotide-RNA + AMP + diphosphate;

CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00200}.
CC -!- SIMILARITY: Belongs to the RNA 3'-terminal cyclase family. Type 1
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00200}.
