Polynucleotide phosphorylase from Synechocystis sp.
recombinant, expressed in E. coli
别名:
PNPase, Polyribonucleotide Nucleotidyltransferase
一般描述
Polynuclotide phosphorlyase in spinach chloroplasts acts as a exonuclease and a poly(A) polymerase.
应用
Polynucleotide phosphorylase has been used in a study to discover that a major function of PNPase is the synthesis of CDP. It has also been used in a study to investigate the enzyme responsible for RNA 3′-tail synthesis in S. coelicolor.
生化/生理作用
Polynucleotide phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3′ to 5′ exoribonuclease activity and a 3′-terminal oligonucleotide polymerase activity.
Polynucleotide phosphorylase localizes to the intermembrane space of mitochondria and has a critical function in regulating mitochondrial homeostasis in human cells.
其他说明
One unit will polymerize 1.0 μmole of ADP, releasing 1.0 μmole of inorganic phosphate in 15 minutes, at pH 9.1 at 37 °C.
Supplied as a solution in 20 mM Hepes buffer pH 7.9, 0.1 mM EDTA, 2 mM DTT, 12.5 mM MgCl2, 60 mM KCl, 20% (w/v) Glycerol

As in other bacteria, 3'-tails are added post-transcriptionally to Streptomyces coelicolor RNA. These tails are heteropolymeric, and although there are several candidates, the enzyme responsible for their synthesis has not been definitively identified. This paper reports on three candidates for

The mechanism of RNA degradation in Escherichia coli involves endonucleolytic cleavage, polyadenylation of the cleavage product by poly(A) polymerase, and exonucleolytic degradation by the exoribonucleases, polynucleotide phosphorylase (PNPase) and RNase II. The poly(A) tails are homogenous, containing only adenosines in

RNase E isolated from Escherichia coli is contained in a multicomponent "degradosome" complex with other proteins implicated in RNA decay. Earlier work has shown that the C-terminal region of RNase E is a scaffold for the binding of degradosome components

Genome comparison permits identification of chromosome regions conserved during evolution. Bacillus subtilis and Escherichia coli are so distant that there exists very few conserved landmarks in their genome organisation. Analysis of the conserved cmk rpsA cluster pinpointed the importance of

The transient existence of small RNAs free of binding to the RNA chaperone Hfq is part of the normal dynamic lifecycle of a sRNA. Small RNAs are extremely labile when not associated with Hfq, but the mechanism by which Hfq
