title: Reevaluation of membrane binding of erythrocyte glutathione reductase (EC 1.6.4.2).
abstract: Data concerning membrane binding of glutathione reductase (GSSG-R) have been reexamined with respect to the following experimental conditions: 1. Haemolysis and membrane preparation; 2. influence of nonionic detergents (Triton X-100, Lubrol PX). Haemolysis and membrane preparations performed at physiological ionic strength, and reduced glutathione concentration do not give any evidence for binding of GSSG-R to the erythrocyte membrane. Under hypotonic conditions of ghost preparation about 2% of the total cellular GSSG-R activity are membrane bound, indicating weak enzyme association at low ionic strength only.
