Formation of racemic pentose-2,4-bisphosphates is demonstrated, starting from glycolaldehyde phosphate and glyceraldehyde-2-phosphate, and induced by mixed valence double layer metal hydroxide minerals. The reactions proceed from dil. aq. reactant solns. ( ...
Thermodynamic feasibility analysis (TFA) has been used as a toot capable of providing additional constraints to the mass balance-based methods of analysis of Metabolic networks (e.g., flux balance analysis). Several publications have recently appeared in w ...
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a key enzyme in the glycolytic metabolism and the production of energy. This probably explains why GAPDH was evidenced as a major therapeutical target in several parasitic diseases; either as a vaccine ca ...
We measured polycrystalline samples of SrRuO3 and both superconducting and nonsuperconducting (hydrogen loaded) ruthenocuprates-Eu1.5Ce0.5RuSr2Cu2O10-x (Ru-1222)-samples using ac susceptibility, Ru 3p x-ray photoemission and Ru 2p x-ray-absorption measurem ...
The primary metabolic route for D-xylose, the second most abundant sugar in nature, is via the pentose phosphate pathway after a two-step or three-step conversion to xylulose-5-phosphate. Xylulose kinase (XK; EC 2.7.1.17) phosphorylates D-xylulose, the las ...
Astrocytes play an important role in nervous system homeostasis. In particular, they contribute to the regulation of local energy metabolism and to oxidative stress defence. In previous experiments, we showed that long-term treatment with interleukin 1alph ...
Carotenoid prodn. by microorganisms, as opposed to chem. synthesis, could fulfill an ever-increasing demand for 'all natural' products. The yeast Phaffia rhodozyma has received considerable attention because it produces the red pigment astaxanthin, commonl ...
The regulation of the eukaryotic cell cycle depends on the action of several related Ser/Thr protein kinases called cyclin-dependent kinases (CDKs), which are transiently activated at specific stages of the cycle, and which are also very promising targets ...
We describe the development of a computational approach for the identification of every possible biochem. reaction from a given set of enzyme reaction rules that allows the de novo synthesis of metabolic pathways composed of these reactions, and the evalua ...
Unambitious syntheses of D-ribose 2-phosphate, 3-phosphate, 4-phosphate, 2,3-diphosphate, 3,4-diphosphate, 2,4-diphosphate, cyclic 2,3-phosphate, cyclic 3,4-phosphate, and cyclic 2,4-phosphate are described. Their 1H- and 31P-NMR data as well as their equi ...
