| RNase T1 | A nuclease endonucleolytically cleaving ribonucleic acids at the 3'-5' link of a guanosine 3'-phosphate residue, producing oligonucleotides terminating in this nucleotide; a transferase (endonuclease) in the first (cyclizing) step, a phosphodiesterase on the second (hydrolyzing) step. Synonym: guanyloribonuclease, RNase N1. (05 Mar 2000) |

| RNase T2 | <enzyme> An enzyme endonucleolytically cleaving RNA to 3'-nucleotides with 2',3'-cyclic nucleotides as intermediates. Synonym: Escherichia coli RNase I, microbial RNase II, plant RNase, RNase N2. (05 Mar 2000) |
| RNase U2 | <enzyme> An enzyme endonucleolytically cleaving RNA to 3'-phospho-mono-and oligonucleotides ending in adenylate or guanylate residues with 2',3'-cyclic phosphate intermediates. (05 Mar 2000) |
| RNase U4 | <enzyme> An enzyme catalyzing the exonucleolytic cleavage of RNA to yield 3'-phosphomononucleotides. Synonym: RNase U4. (05 Mar 2000) |
