Metabolism of alternative substrates and the bioenergetic status of EMT6 tumor cell spheroids
Autor: J P, Wehrle, C E, Ng, K A, McGovern, N R, Aiken, D C, Shungu, E M, Chance, J D, Glickson
Publikováno v: NMR in biomedicine. 13(6)
In order to evaluate the ability of EMT6/Ro multicellular spheroids to utilize various pathways of energy production, (13)C and (31)P MRS have been employed to monitor the metabolism of glucose, glutamine, acetate and propionate. EMT6/Ro spheroids pe

Comparison of the kinetic properties of the lipid- and protein-kinase activities of the p110alpha and p110beta catalytic subunits of class-Ia phosphoinositide 3-kinases
Autor: C A, Beeton, E M, Chance, L C, Foukas, P R, Shepherd
Publikováno v: The Biochemical journal.
Growth factors regulate a wide range of cellular processes via activation of the class-Ia phosphoinositide 3-kinases (PI 3-kinases). We directly compared kinetic properties of lipid- and protein-kinase activities of the widely expressed p110alpha and

Mathematical analysis of isotope labeling in the citric acid cycle with applications to 13C NMR studies in perfused rat hearts
Autor: E M Chance, K Kobayashi, Steven H. Seeholzer, John R. Williamson
Publikováno v: Journal of Biological Chemistry. 258:13785-13794
Rat hearts have been perfused in vitro with 5 mM glucose and either 5 mM acetate or 1 mM pyruvate to achieve steady state conditions, followed by replacement of the acetate with 90% enriched [2-13C]acetate or pyruvate with 90% enriched [3-13C]pyruvat

Low-temperature kinetics of the reactions of fully reduced membrane-bound cytochrome oxidase with oxygen in the Soret, α and near-infrared regions
Autor: G M Clore, E M Chance
Publikováno v: Biochemical Journal. 177:613-621
The kinetics of the reaction of fully reduced membrane-bound cytochrome oxidase with O2 obtained in the Soret, alpha and near-i.r. regions were analysed, and the contributions of the three intermediates of the reaction [Clore & Chance (1978) Biochem.

The mechanism of reaction of fully reduced membrane-bound cytochrome oxidase with oxygen at 176K
Autor: G M Clore, E M Chance
Publikováno v: Biochemical Journal. 173:799-810
1. The results of non-linear optimization studies on the mechanism of reaction of fully reduced cytochrome oxidase with O2 at 176K are presented. The analysis is carried out on data obtained by means of dual-wavelength multi-channel spectroscopy at t

The activity of creatine kinase in frog skeletal muscle studied by saturation-transfer nuclear magnetic resonance
Autor: D. R. Wilkie, E M Chance, Dg Gadian, G. K. Radda, Mj Dawson, Truman R. Brown
Publikováno v: The Biochemical journal. 194(1)
1. The activity of creatine kinase in intact anaerobic frog muscle at 4 degrees C at rest and during contraction was investigated by using saturation-transfer 31P n.m.r. 2. At rest, the measured forward (phosphocreatine to ATP) reaction flux was 1.7
