| Ribonuclease T2 from Aspergillus oryzae, Recombinant | Aspergillus oryzae Ribonuclease T2 is a member of the RNase T2 family of endonucleases that are present in a wide variety of microbial, plant and animal species. In contrast to Aspergillus oryzae Ribonuclease T1, which is an exclusively guanylic-acid specific endonuclease, all RNase T2-like enzymes are essentially base non-specific. However, RNase T2 endonucleases from different species can show slight base preferences. The fungal enzymes, including Aspargillus oryzae RNaseT2, show slight base preference in the following order: A>G>C, U. RNase T2 cleaves between the 3-phosphate residue of one base and the 5-OH residue of the adjacent nucleotide forming a 2, 3-cyclic phosphate intermediate followed by the generation of oligonucleotides with 3-phosphate residues. This enzyme is also used as a non-mammalian source of RNase in various applications. Group: Enzymes. Synonyms: Ribonuclease T2; RNase T2; Ribonuclease. Enzyme Commission Number: EC 3.1.27.1. Rnase.

| (RS)-1-benzyl-1,2,3,4-tetrahydroisoquinoline N-methyltransferase | Broad substrate specificity for (RS)-1-benzyl-1,2,3,4-tetrahydroisoquinolines; including coclaurine, norcoclaurine, isococlaurine, norarmepavine, norreticuline and tetrahydropapaverine.

The enzyme was earlier termed norreticuline N-methyltransferase. However, norreticuline has not been found to occur in nature and that name does not reflect the broad specificity of the enzyme for (RS)-1-benzyl-1,2,3,4-tetrahydroisoquinolines. Group: Enzymes.
