Transient behaviour towards the stable limit cycle in the Selkov model of Glycolysis: A physiological disorder [PDF]
Physica A 567 (2021) 125684, 2020 A simplified model for the complex glycolytic process was historically proposed by Selkov. It showed the existence of stable limit cycle as an example of Poincare-Bendixson theorem. This limit cycle is nothing but the time eliminated Lissajous plot of the concentrations of Adenosine-diphosphate (ADP) and Fructose-6-phosphate (F6P) of a normal/healthy ...

The structure of Rph, an exoribonuclease from Bacillus anthracis, at 1.7 angstrom resolution [PDF]
, 2008 Maturation of tRNA precursors into functional tRNA molecules requires trimming of the primary transcript at both the 5' and 3' ends. Cleavage of nucleotides from the 3' stem of tRNA precursors, releasing nucleotide diphosphates, is accomplished in ...

A procedure for the preparation and isolation of nucleoside-5’-diphosphates
Beilstein Journal of Organic Chemistry, 2015 Tris[bis(triphenylphosphoranylidene)ammonium] pyrophosphate (PPN pyrophosphate) was used in the SN2 displacements of the tosylate ion from 5’-tosylnucleosides to afford nucleoside-5’-diphosphates. Selective precipitation permitted the direct isolation of

Structure of a membrane-embedded prenyltransferase homologous to UBIAD1. [PDF]
PLoS Biology, 2014 Membrane-embedded prenyltransferases from the UbiA family catalyze the Mg2+-dependent transfer of a hydrophobic polyprenyl chain onto a variety of acceptor molecules and are involved in the synthesis of molecules that mediate electron transport ...

Dynamics of Microtubule Growth and Catastrophe [PDF]
Phys. Rev. E 76, 041907 (2007), 2007 We investigate a simple model of microtubule dynamics in which a microtubule evolves by: (i) attachment of guanosine triphosphate (GTP) to its end at rate lambda, (ii) GTP converting irreversibly to guanosine diphosphate (GDP) at rate 1, and (iii) detachment of GDP from the end of a microtubule at rate mu.

Isolation and characterization of Pisum sativum apyrases, PsNTP9 and PsNTP9-DM, cloned and expressed in Escherichia coli [PDF]
, 2019 Adenosine triphosphate (ATP) is widely known as a fuel source for many biochemical processes, and to a lesser degree also as a signaling molecule in plants and animals.

Dynamics of Microtubule Instabilities [PDF]
J. Stat. Mech. (2007) L05004, 2007 We investigate the dynamics of an idealized model of microtubule growth that evolves by: (i) attachment of guanosine triphosphate (GTP) at rate lambda, (ii) conversion of GTP to guanosine diphosphate (GDP) at rate 1, and (iii) detachment of GDP at rate mu. As a function of these rates, a microtubule can grow steadily or its length can fluctuate wildly.

Acetylation regulates ribonucleotide reductase activity and cancer cell growth
Nature Communications, 2019 Ribonucleotide reductase (RNR) catalyzes the de novo synthesis of deoxyribonucleoside diphosphates to provide dNTP precursors for DNA synthesis. Here the authors show that the availability of dNTPs, DNA replication, and cellular proliferation, are ...
