RNase BN is active on both double- and single-stranded RNA but duplex RNA is preferred. Displays a profound base specificity, showing no activity on runs of C residues. Digestion by RNase BN leads to 3-mers as the limit products, but the rate slows on molecules shorter than 10 nucleotides in length. RNase BN acts as a distributive exoribonuclease on some substrates, releasing mononucleotides and a ladder of digestion products. RNase BN also cleaves endonucleolytically, releasing 3' fragments as short as 4 nucleotides
