Quantum information in the Posner model of quantum cognition [PDF]
, 2019 Matthew Fisher recently postulated a mechanism by which quantum phenomena could influence cognition: Phosphorus nuclear spins may resist decoherence for long times, especially when in Posner molecules. The spins would serve as biological qubits.

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 ...

AZT exerts its antitumoral effect by telomeric and non-telomeric effects in a mammary adenocarcinoma model [PDF]
, 2016 Limitless replicative potential is one of the hallmarks of cancer that is mainly due to the activity of telomerase. This holoenzyme maintains telomere length, adding TTAGGG repetitions at the end of chromosomes in each cell division.

Transcriptome analysis of bitter acid biosynthesis and precursor pathways in hop (
BMC Plant Biology, 2013 Background Bitter acids (e.g. humulone) are prenylated polyketides synthesized in lupulin glands of the hop plant (Humulus lupulus) which are important contributors to the bitter flavour and stability of beer.

Guanosine 5‘-diphosphate-3‘-diphosphate inhibition of adenylosuccinate synthetase.
Journal of Biological Chemistry, 1979 The mechanism of ppGpp inhibition of adenylosuccinate synthetase (EC 6.3.4.4) was examined. Initial rate kinetic studies demonstrate the ppGpp inhibition is competitive with respect to GTP and noncompetitive with respect to L-aspartate and IMP. This is in contrast to an earlier report (Gallant, J., Irr, J., and Cashel, M. (1971) J. Biol. Chem.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Golgi-located NTPDase1 of Leishmania major is required for lipophosphoglycan elongation and normal lesion development whereas secreted NTPDase2 is dispensable for virulence. [PDF]
PLoS Neglected Tropical Diseases, 2014 Parasitic protozoa, such as Leishmania species, are thought to express a number of surface and secreted nucleoside triphosphate diphosphohydrolases (NTPDases) which hydrolyze a broad range of nucleoside tri- and diphosphates.
