    Notes: Summary An NADH-ferricyanide reductase activity resistant to inactivation by cytochemical procedures was examined during decidualization of rat endometrium. Resistant activity was restricted to plasma membranes, distal elements of the Golgi apparatus, and discoid cisternae and cytoplasmic vesicles of decidual cells of endometrium of the pseudopregnant rat on days 3, 4, 5, 7, and 9, after mating. The procedure reduced or eliminated any evidence of NADH-ferricyanide reductase activity from other cellular components such as endoplasmic reticulum, nuclei, and mitochondria. The observations of the glutaraldehyde-resistant reductase in both plasma membranes and discoid cisternae may indicate a role for the latter in the biosynthesis of plasma membranes during decidualization when massive cell proliferation and membrane biosynthesis occur. The origin of the discoid cisternae is tentatively ascribed to the mature faces of the Golgi apparatus.

    Inhibition of 5′-nucleotidase by concanavalin A: Evidence for localization on the outer surface of the plasma membrane (1976)

    Notes: Summary 5′-Nucleotidase activity of rat liver plasma membrane is markedly inhibited by concanavalin A. Taken together with a unilateral pattern of labelling of concanavalin A binding sites with hemocyanin, the results indicate that an allosteric site of the enzyme is at the outer surface of the membrane.

    NADH-ascorbate free radical and -ferricyanide reductase activities represent different levels of plasma membrane electron transport (1993)

    Notes: Abstract Plasma membranes isolated from rat liver by two-phase partition exhibited dehydrogenase activities for ascorbate free radical (AFR) and ferricyanide reduction in a ratio of specific activities of 1 : 40. NADH-AFR reductase could not be solubilized by detergents from plasma membrane fractions. NADH-AFR reductase was inhibited in both clathrin-depleted membrane and membranes incubated with anti-clathrin antiserum. This activity was reconstituted in plasma membranes in proportion to the amount of clathrin-enriched supernatant added. NADH ferricyanide reductase was unaffected by both clathrin-depletion and antibody incubation and was fully solubilized by detergents. Also, wheat germ agglutinin only inhibited NADH-AFR reductase. The findings suggest that NADH-AFR reductase and NADH-ferricyanide reductase activities of plasma membrane represent different levels of the electron transport chain. The inability of the NADH-AFR reductase to survive detergent solubilization might indicate the involvement of more than one protein in the electron transport from NADH to the AFR but not to ferricyanide.
