EC 3.1.26.10     
Accepted name: ribonuclease IX
Reaction: Endonucleolytic cleavage of poly(U) or poly(C) to fragments terminated by 3′-hydroxy and 5′-phosphate groups
Other name(s): poly(U)- and poly(C)-specific endoribonuclease
Comments: Acts on poly(U) and poly(C), with a higher affinity for poly(C), but does not act on poly(A) or poly(G).
