[Article in Japanese] Matsuo K, Higuchi S, Tsuboi M. PMID: 4567711 [PubMed - indexed for MEDLINE] Publication Types: Review; MeSH Terms. Adenosine Diphosphate/metabolism; Escherichia coli/enzymology; Methods; Phosphorus Isotopes; Polynucleotides/chemical synthesis; Polyribonucleotide Nucleotidyltransferase/analysis Polynucleotide Phosphorylase (PNPase) All known phosphorylases share catalytic and structural properties . Activation. 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. 2012-11-21 · Deletion of the pnp gene, encoding polynucleotide phosphorylase, an RNA processing enzyme and a component of the RNA degradosome, results in increased biofilm formation in Escherichia coli. This effect is particularly pronounced in the E. coli strain C-1a, in which deletion of the pnp gene leads to strong cell aggregation in liquid medium. Polynucleotide Phosphorylase: In 1955, Marianne Grunberg-Manago and Severo Ochoa reported the isolation of an enzyme that catalyzed the synthesis of RNA. Their work built upon the earlier work of Jerard Hurwitz & J.J. Furth who performed experiments to see if isolated E. coli protein fractions could polymerize radioactively labeled nucleotides . Polynucleotide Phosphorylase ( PNPase) is a bifunctional enzyme with a phosphorolytic 3' to 5' exoribonuclease activity and a 3'-terminal oligonucleotide polymerase activity.

Transformability of a comR (pnpA) mutant is 1–5% of that seen in comR + strains. Cloning and sequencing identified ComR as polynucleotide phosphorylase (PNPase).

WADE HE, LOVETT S. The Biochemical Journal, 01 Nov 1961, 81: 319-328 DOI: 10.1042 Nostoc polynucleotide phosphorylase 2047 were sealed into plastic bags with 100 ml incubation mixtures consisting of CAPS buffer, 10 ~M-ADP and, when required, 0.05 mg ml-I poly(U) as primer. The Polyguanylic acid (poly(G)) was synthesized from GDP in a yield of 60-75% by Thermus thermophilus polynucleotide phosphorylase (polyribonucleotide: orthophosphate nucleotidyltransferase, EC 2.7.7.8) at 70°C, pH 8.5 in the presence of Mg 2+. Neisseria meningitidis autoaggregation is an important step during attachment to human cells. Aggregation is mediated by type IV pili and can be modulated by accessory pilus proteins, such as PilX, and posttranslational modifications of the major pilus subunit PilE. The mechanisms underlying the regulation of aggregation remain poorly characterized. Polynucleotide phosphorylase (PNPase) is a 3 Aug 27, 2013 Polynucleotide phosphorylase(1) (PNPase) catalyzes stepwise phosphorolysis of the 3′-terminal phosphodiesters of RNA chains to yield Polynucleotide phosphorylase from Synechocystis sp.
