General annotation (Comments)

Function

Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing By similarity. HAMAP-Rule MF_00200

Catalytic activity

ATP + RNA 3'-terminal-phosphate = AMP + diphosphate + RNA terminal-2',3'-cyclic-phosphate. HAMAP-Rule MF_00200

Subcellular location

Cytoplasm Potential HAMAP-Rule MF_00200.

Sequence similarities

Belongs to the RNA 3'-terminal cyclase family. Type 1 subfamily.
