WebFigure 6.1 A Polynucleotide chain Two nucleotides are linked through 3 '-5 ' phosphodiester linkage to form a dinucleotide. More nucleotides can be joined in such a manner to form a polynucleotide chain. A polymer thus formed has at one end a free phosphate moiety at 5 '-end of sugar, which is referred to as 5’-end of polynucleotide chain. Similarly, at the other … WebParallel Colorimetric Quantification of Choline and Phosphocholine as a Method for Studying Choline Kinase Activity in Complex Mixtures

WebPolynucleotide Phosphorylase (PNPase) is a bifunctional enzyme with a phosphorolytic 3' to 5' exoribonuclease activity and a 3'-terminal oligonucleotide polymerase activity. [2] That is, it dismantles the RNA chain starting at the 3' end and working toward the 5' end. [1] It also synthesizes long, highly heteropolymeric tails in vivo.It accounts for all of the observed … Phosphorylase a is the more active R form of glycogen phosphorylase that is derived from the phosphorylation of the less active R form, phosphorylase b with associated AMP. The inactive T form is either phosphorylated by phosphoylase kinase and inhibited by glucose, or dephosphorylated by phosphoprotein phosphatase with inhibition by ATP and/or glucose 6-phosphate.
