RNAse activity review
I did a few searches, just for fun, but all I came up with was:


  Yuhong Zuo and Murray P. Deutscher "Exoribonuclease superfamilies: structural analysis and phylogenetic distribution"
  (2001) Nucl. Acids Res. 29 (5): 1017-1026. doi: 10.1093/nar/29.5.1017


Not very recent, but it's open access. It might be possible to search for more recent papers that have cited this. Although I haven't tried it myself, I found suggestions for doing this at https://www.bc.edu/libraries/help/howdoi/howto/pubcitation.html.
