Structural insights into the catalytic mechanism of phosphate ester hydrolysis by dUTPase.
dUTPase is essential to keep uracil out of DNA. Crystal structures of substrate (dUTP and alpha,beta-imino-dUTP) and product complexes of wild type and mutant dUTPases were determined to reveal how an enzyme responsible for DNA integrity functions. A kinetic analysis of wild type and mutant dUTPases was performed to obtain relevant mechanistic information in solution. Substrate hydrolysis is sh...
متن کاملThermodynamics of the hydrolysis of sucrose.
A thermodynamic investigation of the hydrolysis of sucrose to fructose and glucose has been performed using microcalorimetry and high-pressure liquid chromatography. The calorimetric measurements were carried out over the temperature range 298-316 K and in sodium acetate buffer (0.1 M, pH 5.65). Enthalpy and heat capacity changes were obtained for the hydrolysis of aqueous sucrose (process A): ...
متن کاملThe free energy of thiol ester hydrolysis.
Thiol esters, such as aeetyl coenzyme A, the principal biological carrier of activated acetyl groups, have generally been supposed to be “energy-rich” compounds; i.e. to have a free energy of hydrolysis at pH 7.0 in the range of -7000 to -14,000 calories per mole. The reported numerical values for the free energy of thiol ester hydrolysis have varied over a wide range (for recent estimates see ...
متن کاملThe pH-dependence of enzymic ester hydrolysis.
The esterases of animal tissues have generally been characterized by their substrate specificity and by their behaviour towards various inhibitors. The irreversible inhibition by organic phosphates, which is due to phosphorylation of the active group (Burgen, 1949; Wilson & Bergmann, 1950a; Aldridge, 1953d), is a common property of most esterases, an interesting exception being the Aesterase of...
متن کاملTriglyceride and cholesteryl ester hydrolysis
Cultured rabbit aortic smooth muscle cells were converted to foam cells by exposure to sonicated lipid droplets of defined composition using an inverted culture technique. Uptake of the lipid droplets by the cells was shown to be dependent on the time of exposure to the droplets and on the mass of droplets presented to the cells. A comparison of the hydrolysis of triolein and cholesteryl oleate...
