Paramagnetic Effects on Nuclear Relaxation in Enzyme-Bound Co(II)-Adenine Nucleotide Complexes: Relative Contributions of Dipolar and Scalar Interactions

摘要

~(31)P NMR measurements on CoADP bound to creatine kinase designed to estimate the relative contribution of scalar and dipolar interactions to ~(31)P spin relaxation rates show that these rates are primarily due to distance-dependent dipolar interactions and that the contribution of the scalar interaction is negligible.
