Polynucleotide phosphorylase
WebQuestion: A random (UG) copolymer was synthesized with polynucleotide phosphorylase using a mixture of 5 parts uracil nucleotide to 1 part guanine nucleotide as the substrate. State which amino acids would be incorporated into the polypeptide product if this random copolymer was used in a cell-free protein synthesis system. WebThe pnp gene encodes polynucleotide phosphorylase, an exoribonuclease involved in RNA processing and degradation. A mutation in the pnp gene was previously identified by our group in a signature-tagged mutagenesis screen designed to search for Salmonella enterica serovar Typhimurium genes required for survival in an ex vivo swine stomach content …

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 … WebFROM READING ABOUT POLYNUCLEOTIDE PHOSPHORYLASE IN BUDAPEST TO BECOMING SEVERO OCHOA'S GRADUATE STUDENT IN NEW YORK.

WebAzotobacter polynucleotide phosphorylase was used to prepare short polyadenylic acid messengers with one cytidine residue at the 3′-end. These polynucleotide messengers produced water-soluble lysine polypeptides with COOH-terminal asparagines, thus confirming that the polynucleotide message is read from the 5′- to 3′-end.
