The Eq+librium Constants of the Adenosine Triphosphate Hydrolysis and the Adenosine Triphosphate- Citrate Lyase Reactions
The observed standard free energy change (AGibs) for the hydrolysis of the terminal pyrophosphate bond of ATP has been experimentally determined under physiological conditions using an entirely new set of reactions. The observed equilibrium constant (K,,bs) for the combined reactions of acetate kinase (EC 2.7.2.1) and phosphate acetyltransferase (EC 2.3.1.8) has been determined at 38”, pH 7.0, ...

متن کاملMechanism of adenosine triphosphate hydrolysis by actomyosin.
The hydrolysis of ATP by acto-HMM has been studied during the transient state using a rapid-mixing apparatus. The rate of substrate binding was slightly slower and the rate of hydrolysis of the first molecule of ATP was essentially the same as for heavy meromyosin (HMM) alone. The rate of acto-HMM dissociation after binding substrate was too fast to measure in a stopped-flow apparatus, conseque...
متن کاملStudies on the Hydrolysis of Adenosine Triphosphate by Spinach Chloroplasts.
During studies on photophosphorylation in cell-free preparations of the blue-green alga, Anabaena variabilis, a photohydrolysis of ATP was found to be induced by high concentrations of cysteine or GSH, while photophosphorylation became inhibited (1, 2). A similar photohydrolysis was also reported with chloroplasts from spinach leaves, but still higher sulfhydryl concentrations were required to ...
متن کاملAdenosine triphosphate inhibition in myosin adenosine triphosphate systems.
Factors affecting inhibition of myosin ATPase by ATP, such as concentration of the enzyme, of ATP, and of the divalent metals, calcium and magnesium, have been studied and the results are reported here. Experiments were carried out under conditions in which no known magnesium effects occurred, so that only the effect of calcium on the nucleoside triphosphatase activity of myosin A could be qual...
