[RNA] 5'-hydroxy-ribonucleotide-3'-[RNA fragment]-lyase (cyclicizing; [RNA fragment]-3'- nucleoside -2',3'-cyclophosphate-forming)

RNA = a 5'-hydroxy-ribonucleotide + n nucleoside-2',3'-cyclophosphates

RNA [CPD:C00046]

This enzyme catalyses endonucleolytic cleavage to 2',3'-cyclic nucleotides. The cyclic products may be hydrolysed to the corresponding 3'-phosphates by 2',3'-cyclic-nucleotide 2'-phosphodiesterase (EC 3.1.4.16). The enzyme from B. subtilis is inhibited by ATP.

EC 4.6.1.22 created 1978 as EC 3.1.27.2, transferred 2028 to EC 4.6.1.22
