Accepted name: |
RNA 2′,3′-cyclic 3′-phosphodiesterase |
Reaction: |
(ribonucleotide)n-2′,3′-cyclic phosphate + H2O = (ribonucleotide)n-2′-phosphate |
Other name(s): |
thpR (gene name); ligT (gene name) |
Systematic name: |
(ribonucleotide)n-2′,3′-cyclic phosphate 3′-nucleotidohydrolase |
Comments: |
The enzyme hydrolyses 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. |
