Thallium diphosphates

, 2020
Three thallium(I) diphosphates with compositions Tl4P2O7, Tl2H2P2O7, Tl2H2P2O7(H2O)0.5 and the mixed-valent thallium(I,III) diphosphate Tl2P2O7 (= TlITlIIIP2O7) were obtained from aqueous solutions using an ion-exchange resin (Tl4P2O7), through thermal ...

Triclinic-Cubic Phase Transition and Negative Expansion in the Actinide IV (Th, U, Np, Pu) Diphosphates

, 2012
The AnP2O7 diphosphates (An = Th, U, Np, Pu) have been synthesized by various routes depending on the stability of the AnIV cation and its suitability for the unusual octahedral environment.

Enzyme kinetics of the mitochondrial deoxyribonucleoside salvage pathway are not sufficient to support rapid mtDNA replication. [PDF]

PLoS Computational Biology, 2011
Using a computational model, we simulated mitochondrial deoxynucleotide metabolism and mitochondrial DNA replication. Our results indicate that the output from the mitochondrial salvage enzymes alone is inadequate to support a mitochondrial DNA ...

Efficient One-Step Syntheses of Isoprenoid Conjugates of Nucleoside 5‘-Diphosphates

, 2016
Isoprenoid conjugates of nucleoside 5‘-diphosphates were efficiently synthesized by one-step nucleophilic displacement reactions of either isoprenyl chlorides or isopentenyl tosylate with nucleoside 5 ...

The Product Specificities of Maize Terpene Synthases TPS4 and TPS10 Are Determined Both by Active Site Amino Acids and Residues Adjacent to the Active Site

Plants, 2020
Terpene synthases make up a large family of enzymes that convert prenyl diphosphates into an enormous variety of terpene skeletons. Due to their electrophilic reaction mechanism—which involves the formation of carbocations followed by hydride shifts and ...

Molecular basis for the plasticity of aromatic prenyltransferases in hapalindole biosynthesis

Beilstein Journal of Organic Chemistry, 2019
Aromatic prenyltransferases (PTases) are enzymes that catalyze Friedel–Crafts reactions between aromatic compounds and isoprenoid diphosphates. In hapalindole biosynthesis, the aromatic PTases AmbP1 and AmbP3 exhibit surprisingly plastic selectivities ...

ENZYMATIC-SYNTHESIS OF UNIFORMLY P-32-LABELED POLYRIBONUCLEOTIDES AND HIGH-SPECIFIC-ACTIVITY RIBONUCLEOSIDE 5'-[ALPHA-P-32]DIPHOSPHATES

, 1985
Uniformly 32P-labeled polyribonucleotides of high specific activity can be rapidly and easily synthesized from commercially available ribonucleoside 5-[alpha-32P]triphosphates by using two enzymes in sequence.

Diphosphates at the 5′ end of the positive strand of yeast L-A double-stranded RNA virus as a molecular self-identity tag

, 2017
The 5′end of RNA conveys important information on self-identity. In mammalian cells, double-stranded RNA (dsRNA) with 5′di- or triphosphates generated during virus infection is recognized as foreign and elicits the host innate immune response.
