title: Stabilization of concanavalin A by metal ligands.
abstract: Metal-free concanavalin A is readily and irreversibly inactivated by temperatures above 60 degrees. Manganese ion completely prevents the thermal aggregation of the protein at 60 and 70 degrees, and partially protects at 80 degrees, but shows no protective properties at 90 degrees. Managanese protection against thrermal aggregation was found to be maximal at pH 4-8. The precipitation between glycogen and Mn2+-stabilized conanavian A is partially inhibited at temperatures greater than 30 degrees, but can be reversed by cooling to room temperature...
