The Preparation and Properties of IV-Hydroxyethyl Derivatives of Adenosine, Adenosine Triphosphate, and Nicotinamide Adenine Dinucleotide*
Previous work shows that replacement of the nicotinamide moiety of nicotinamide adenine dinucleotide with other substituted pyridines leads to a useful series of analogues of this coenzyme (3, 4). The present communication describes the preparation and properties of a different series of analogues obtained by systematic modification of the adenine moiety of NAD. The only adenine-modified analog...

متن کاملStudies on Adenosine Triphosphate Transphosphorylases
The isolation of the crystalline enzymes, adenosine triphosphate-creatine transphosphorylase (1) and adenosine triphosphate-adenosine 5’-phosphate transphosphorylase (2), made possible a comparative approach to the general problem of the mechanism of action of the adenosine triphosphate transphosphorylases. The present series of papers extends earlier studies from this laboratory on these enzym...
متن کاملThe Enthalpy Change on Adenosine Triphosphate
The energetics of ATP’ hydrolysis to ADP and P have been studied previously by combining either thermal (1, 2) or free energy (3-6) data for a number of chemical reactions according to the usual procedures of chemical thermodynamics. Such calculations, however, suffer from the fact that the uncertainties in each measurement are compounded in the final result. The ATPase properties of myosin off...
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...
