Mechanism of Exchange in the Mnn-ATP System from Fourier Transform Nuclear Magnetic Resonance and Electron Paramagnetic Resonance Data

Abstract

Nuclear spin relaxation studies have been performed on the MnII–ATP system.

Longitudinal and transverse relaxation times of water protons have been measured and their dependence upon the concentration of the ligand 5′–ATP has been investigated. Temperature and pH effects on both electron and nuclear relaxation rates have been analysed and discussed.
