ENZYME entry: EC 2.7.7.84

Accepted Name
2'-5' oligoadenylate synthase.
Reaction catalysed
3 ATP <=> 5'-triphosphoadenylyl-(2'->5')-adenylyl-(2'->5')-adenosine + 2 diphosphate
Comment(s)
  • 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.
