Kinetics of Hydrogen-Deuterium Exchange of 8-CH Groups in Adenosine 5'-Monophosphate and Guanosine 5'-Monophosphate by Laser Raman Spectroscopy
Sang Kyu Kim, Myung Soo Kim, Se Won Suh
The rate constants of the hydrogen-deuterium exchange of 8-CH groups in 5'-rAMP and 5'-GMP were measured by laser Raman spectroscopy. The Arrhenius activation energies calculated from the rate constants measured as a function of temperature were similar for both compounds. However, the effects of pD on exchange rate constants were different for the two compounds. Our kinetic data support the exchange reaction mechanism involving an ylide type intermediate.
