ID 4.6.1.22 DE Bacillus subtilis ribonuclease. AN bacterial RNA lyase. CA RNA = a 5'-hydroxy-ribonucleotide + n nucleoside-2',3'-cyclophosphates. CC -!- This enzyme catalyzes endonucleolytic cleavage to 2',3'-cyclic CC nucleotides. CC -!- The cyclic products may be hydrolyzed to the corresponding CC 3'-phosphates by EC 3.1.4.16. CC -!- The enzyme from Bacillus subtilis is inhibited by ATP. CC -!- Formerly EC 3.1.27.2. DR U2UMQ6, CS12A_ACISB; A0Q7Q2, CS12A_FRATN; //
