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 inS. coelicolor.
生化/生理作用
Polynucleotide phosphorylase localizes to the intermembrane space of mitochondria and has a critical function in regulating mitochondrial homeostasis in human cells.
Polynucleotide phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3′ to 5′ exoribonuclease activity and a 3′-terminal oligonucleotide polymerase activity.
单位定义
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
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 ℃.
