Hydrolysis of nucleoside phosphates: IV.* The metal ion - nucleic base interaction in the Cu2+-promoted dephosphorylation of the 5′-di- and 5′-triphosphates of cytidine, inosine and guanosine, and their protection toward hydrolysis by coordination to Cu(2,2′-bipyridyl)2+

The dephosphorylation of CTP, GTP, ITP, ATP, CDP, GDP, IDP and ADP was characterized by measuring the first-order rate constant (50 degrees; I = 0.1, NaClO4) in dependence on pH (2 to 10). Except with CTP and CDP, the reactions are significantly acce

On the kinetics and mechanism of the catalase-like activity of diaquocobinamide
Autor: Bernhard Prijs, Helmut Sigel, Peter Rapp, Friedemann Dinglinger
Publikováno v: Journal of Inorganic and Nuclear Chemistry. 39:179-184
The disproportionation of H2O2, catalyzed by diaquocobinamide (CoIIICob), was investigated in the pH range 2–10 by measuring the initial rate, νin0 = d[ O 2 ] d t (Ms−1), of the increase in the concentration of O2 (25°C; [Na+] = 0.1). In contra

Metal ion/buffer interactions. Stability of alkali and alkaline earth ion complexes with triethanolamine (tea), 2-amino-2(hydroxymethyl)-1,3-propanediol (tris)and 2-[bis(2-hydroxyethyl)-amino] 2(hydroxymethyl)-1,3-propanediol (Bistris) in aqueous and mixed solvents

The acidity constants of the protonated buffers given in the title, i.e. of H(Tea)+, H(tris)+ and H(Bistris)+, have been measured at 25 °C in water, 50% aqueous dioxane or methanol, and in 75 or 90% dimethylsulfoxide (Dmso) with tetramethylammonium
