5'-3' exoribonuclease 1 (Xrn1)

Major 5'-3' exoribonuclease involved in mRNA decay. Required for its 5'-3'-processing of the G4 tetraplex-containing DNA and RNA substrates.

The kinetic of hydrolysis is faster for G4 RNA tetraplex than for G4 DNA tetraplex and monomeric RNA tetraplex. Binds into RNA and DNA.
