Enzyme Information
| 2.7.7.84 |
2'-5' oligoadenylate synthase.
based on mapping to UniProt P00973
3 ATP = pppA2'p5'A2'p5'A + 2 diphosphate.
-!- The enzyme is activated by binding to double-stranded RNA. -!- The resulting product binds to and activates RNase L, which subsequently degrades the RNA. -!- Oligoadenylates of chain lengths 2, 4 and 5 are also produced. -!- The dimer does not have any known biological activity.
