Abstract

The selective and nonselective longitudinal relaxation rates were measured for glycyl-l-tyrosine protons in the presence of Zn-carboxypeptidase A. Unlike the non-selective relaxation rates, the selective rate was found to be particularly sensitive to the presence of the enzyme. From the nonselective/selective ratio, the correlation times of the free and bound substrate were evaluated.
