Names: Nidoviral uridylate-specific endoribonuclease (NendoU) domain
Function: Among the Nsps found in Nidovirales, nonstructural protein 15
 (nsp15) from coronaviruses and Nsp11 from arteriviruses contain in their C-
 terminal region a conserved endoribonuclease domain called nidoviral
 uridylate-specific endoribonuclease (NendoU) with cleavage specificity for
 single- and double-stranded RNA 5' of uridine nucleotides to produce a 2'-3'-
 cyclic phosphate end product.
