- A widely distributed family of related enzymes found in protozoans,
plants, bacteria, animals and viruses that cleave ssRNA 3'-phosphate
group with little base specificity.
- The enzyme catalyzes a two-stage endonucleolytic cleavage.
- The first reaction produces 5'-hydroxy-phosphooligonucletides and
3'-phosphooligonucleotides ending with a 2',3'-cyclic phosphodiester,
which are released from the enzyme.
- The enzyme then hydrolyzes the cyclic products in a second reaction
that takes place only when all the susceptible 3',5'-phosphodiester
bonds have been cyclised.
- The second reaction is a reversal of the first reaction using the
hydroxyl group of water instead of the 5'-hydroxyl group of ribose.
- The overall process is that of a phosphorus-oxygen lyase followed by
hydrolysis to form the 3'-nucleotides.
- Formerly EC 2.7.7.17, EC 3.1.4.23 and EC 3.1.27.1.
