Type: | Domain | Name: | PNPase/RNase PH domain |
Description: | Polynucleotide phosphorylase (PNPase) is a polyribonucleotide nucleotidyl transferase that degrades mRNA in prokaryotes. Polynucleotide phosphorylase and the Ribonuclease PH (RNase PH) family possess a common domain represented by this entry. This suggests similar structures and mechanisms of action for these 3'-->5' phosphorolytic enzymes []. In the case of PNPase, the core domain is found duplicated []. | Short Name: | PNPase/RNase_PH_dom |
