Polynucleotide phosphorylase (PNPase) is a polynucleotide nucleotidyl transferase (E. C. 2.7.7.8) that is involved in mRNA degradation in prokaryotes. PNPase structure analysis has been performed in Streptomyces antibioticus; this revealed the presence of five domains: two ribonuclease PH (RPH)-like …

Polynucleotide chain has direction. They are represented in 5’---> 3’ and 3’----> 5’ directions. Each polynucleotide chain has 2 ends. The second polynucleotide may also include a 5′-cap structure. The method may also involve the further step of ligating a fourth polynucleotide comprising a poly-A region at the 3′-terminus of the third polynucleotide.

T4 polynucleotide kinase (Pnk) is the founding member of a family of 5'-kinase/3'-phosphatase enzymes that heal broken termini in RNA or DNA by converting 3'-PO(4)/5'-OH ends into 3'-OH/5'-PO(4) ends, which are then suitable for sealing by RNA or DNA ligases. Here we employed site-directed mutagenes … Polynucleotide Phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3' to 5' exoribonuclease activity and a 3'-terminal oligonucleotide polymerase activity. That is, it dismantles the RNA chain starting at the 3' end and working toward the 5' end. It also synthesizes long, highly heteropolymeric tails in vivo.It accounts for all of the observed residual polyadenylation in Bifunctional polynucleotide phosphatase kinase is an enzyme that in humans is encoded by the PNKP gene. PNKP has been shown to interact with DNA polymerase Enzymes that have phosphorolytic 3 to 5 exoribonuclease activity break phosphodiester bond RNase PH Polynucleotide Phosphorylase PNPase All known nucleotidase EC 3 1. 3 32: polynucleotide 3 - phosphatase EC 3 1. 3 33: polynucleotide 5 T4 phage polynucleotide kinase (PNK) was identified over 35 years ago and has become a staple reagent for molecular biologists.

Search results for polynucleotide at Sigma-Aldrich. Summary: This locus represents a gene involved in DNA repair. In response to ionizing radiation or oxidative damage, the protein encoded by this locus catalyzes 5' phosphorylation and 3' dephosphorylation of nucleic acids.

DNA has a double helix structure. The outer edges are formed by alternating deoxyribose sugar molecules and phosphate groups, which make up the sugar-phosphate backbone. The two strands run in opposite directions, one going in a 3' to 5' direction and the other going in a 5' to 3' direction.
