A consideration of the effects of added solutes on the activity of bovine superoxide dismutase.

M E McAdam.   

Abstract

Pulse radiolysis was used to study the effects of changing the concentration of buffer and added salts on the activity of bovine superoxide dismutase. The results are discussed with reference to other work and are interpreted mainly in terms of ionic-strength effects. The effects are best considered as empirical parameters, which are essential for comparative activity measurements. The specific activity of the enzyme was higher than found in previous pulse-radiolysis studies.
