Summary
Plasma membranes (PM) from maize roots (Zea mays L.) were isolated by aqueous two-phase partitioning. The isolated membrane fraction showed a 4.6-fold enrichment in specific activity of the PM marker enzyme vanadate-sensitive, Mg2+-ATPase over a microsomal pellet collected at 50,000 × g. Activities of marker enzymes for mitochondria, endoplasmic reticulum, tonoplast, and Golgi apparatus were low or not detectable in the PM fraction. Quantitative morphometric analysis using the PM-specific silicotungstic acid stain showed the fraction to be > 92% PM vesicles. Using detergent stimulation of ATPase activity as a measure of structurally linked latency, greater than 90% of the PM vesicles were oriented with the cytoplasmic surface inside.
An electron transport activity was investigated in the PM fraction. The rate of NADH oxidation in the absence of an artificial electron acceptor was < 167pkat·mg protein−1; however, NADH catalysed the reduction of a variety of artificial electron acceptors including ferricyanide (2.6 nkat·mg protein−1), cytochromec (0.8 nkat·mg protein−1), a tetrazolium derivative (0.6 nkat·mg protein−1) and dichlorophenol indophenol (0.4 nkat·mg protein−1). While the NADH-dependent ferricyanide and dichlorophenol indophenol reductases were stimulated ⩾ 6-fold by 0.025% (v/v) Triton X-100, the cytochromec and INT reductases were not greatly stimulated. Washing membranes with high salt significantly decreased the NADH-dependent, and eliminated the NADPH-dependent, ferricyanide reductase activity measured in the absence of detergent. These results suggest that NADH was oxidized on the extracytoplasmic surface of the membrane; however, a significant portion of this activity was extrinsic and may have originated from cytoplasmic contamination during isolation. The greater portion of the PM-associated NAD(P)H oxidation and/or ferricyanide reduction was catalyzed on sites not exposed to the outer surface of the membrane.
