生物活性: Ribonulease T1, Aspergillus oryzae (Rnase T1), is commonly used in biochemical research. Ribonuclease T1 is an endonuclease that can specifically degrade single stranded RNA. Ribonuclease T1 can form nucleoside 2 ', 3 '-cyclic phosphoric acid intermediates to cut the phosphodiester bond between 3' -guanosine residues and adjacent nucleoside 5 '-OH groups to produce 3' -GMP terminal oligonucleotides.
