This has led to the recognition that these RNases are present in the whole vertebrate sub-phylum. In fact, they comprise the only enzyme family unique to vertebrates. Four RNases from zebrafish (Danio rerio) have been previously reported, with a very low RNase activity, some endowed, like human angiogenin, with powerful angiogenic and bactericidal activities. Here we report the three-dimensional structure, the thermodynamic behaviour, and the biological properties of a novel zebrafish RNase, ZF-RNase-5. The investigation of its structural and functional properties, extended to all other sub-family members, provides an inclusive description of the whole zebrafish RNase sub-family. A new RNase sheds light on the RNase/angiogenin subfamily from zebrafish.,Pizzo E, Merlino A, Turano M, Russo Krauss I, Coscia F, Zanfardino A, Varcamonti M, Furia A, Giancola C, Mazzarella L, Sica F, D'Alessio G Biochem J. 2010 Nov 4.
