Oxidative inhibition of Ca2+-ATPase in the rabbit lens.

D Borchman1, C A Paterson, N A Delamere.   

Abstract

Hydrogen peroxide inhibition of maximum Ca2+-ATPase and Na+,K+-ATPase activity was measured in a membrane-enriched preparation of rabbit lens cortical fibers and epithelium. At 5 X 10(-6) M hydrogen peroxide maximum Ca2+-ATPase activity was inhibited by 39%, while maximum Na+,K+-ATPase activity was stimulated. Ca2+-ATPase activity was almost completely inhibited at 5 X 10(-4) M hydrogen peroxide, in comparison to Na+,K+-ATPase activity, which was only inhibited by 28% at a concentration of hydrogen peroxide an order of magnitude larger. The addition of catalase to hydrogen peroxide-pretreated samples did not reverse the inhibition of Ca2+-ATPase by hydrogen peroxide.
