Thermochemistry of Lysozyme‐Inhibitor Binding

Abstract
The binding of saccharide inhibitors to lysozyme has been studied using a microcalorimetric method. Measurements have been performed with N‐acetyl‐d‐glucosamine (pH 5 and 25 and 40°C), tri[N‐acetyl‐d‐glucosamine] (pH 2, 5 and 7.6 at 25°C and pH 5 at 40°C) and with tetra‐[N‐acetyl‐d‐glucosamine] (pH 2, 5 and 7.6 at 25°C). From the results of the calorimetric measurements values for ΔG0, ΔH0, ΔS0, and ΔCp0 were derived for the binding processes.In addition to the saccharide‐binding reactions, some model experiments were performed.
