Enzyme Information

3.1.4.58
RNA 2',3'-cyclic 3'-phosphodiesterase.
based on mapping to UniProt Q8U4Q3
(Ribonucleotide)(n)-2',3'-cyclic phosphate + H(2)O = (ribonucleotide)(n)- 2'-phosphate.
-!- The enzyme hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'-phosphomonoester. -!- In vitro the enzyme can also ligate tRNA molecules with 2',3'-cyclic phosphate to tRNA with 5'-hydroxyl termini, forming a 2'-5' phosphodiester linkage. -!- However, the ligase activity is unlikely to be relevant in vivo.
