4.6.1.22 |
| Accepted name: |
Bacillus subtilis ribonuclease |
| Reaction: |
RNA = a 5′-hydroxy-ribonucleotide + n nucleoside-2′,3′-cyclophosphates |
| Other name(s): |
Proteus mirabilis RNase; ribonucleate nucleotido-2′-transferase (cyclizing); bacterial RNA lyase; Bacillus subtilis intracellular ribonuclease |
| Systematic name: |
[RNA] 5′-hydroxy-ribonucleotide-3′-[RNA fragment]-lyase (cyclicizing; [RNA fragment]-3′- nucleoside -2′,3′-cyclophosphate-forming) |
| Comments: |
This enzyme catalyses endonucleolytic cleavage to 2′,3′-cyclic nucleotides. The cyclic products may be hydrolysed to the corresponding 3′-phosphates by 2′,3′-cyclic-nucleotide 2′-phosphodiesterase (EC 3.1.4.16). The enzyme from B. subtilis is inhibited by ATP. |
